Tim Bray just posted a nice blog piece about his new phone: a pre-production Nexus Galaxy running Android 4.0 (code-named “Ice Cream Sandwich”). There are some really nice features in this release, which is, of course, what we’ve come to expect. These days, competition in many markets is driven by features, and less attention is given to price, performance, quality, and customer service.
But will I ever get to use these features? Here’s the comment I posted on Tim’s piece:
Yes, Tim, it all looks very nice. But I’m still waiting for AT&T to get around to updating my Samsung Infuse 4G from Froyo to Gingerbread (promised in August, already shipping in Canada). I have no idea if AT&T and Samsung will ever put Ice Cream Sandwich on the Infuse, let alone when. I read your account of the new features, but I have no idea whether it’s relevant to me.
For me, this is the biggest bug in the Android business model compared with iOS: it’s completely unpredictable. All of the players – Google, handset makers and carriers – contribute to the mess. And so I’m not surprised that so many apps are so unstable: the test matrix is ridiculously big.
In contrast, when an iOS release comes out, I know exactly what it will run on, and which features will be available on my device. Moreover I can install it immediately.
This summer, I decided to try life outside the “walled garden” and replaced my iPhone 4 with the best Android device then available. I have to report that so far, life outside the wall sucks. This is a shame. I guess I could hack it, but great products shouldn’t need hacking….
Yesterday I had the last post-op inspection for my right eye, and got the paperwork for the countdown to next Tuesday’s procedure for my left. By now, two of the eye drops had run out, but I was still taking the steroid Durezol. My doctor decided that by now it was doing slightly more harm than good (probably elevating the intraocular pressure a bit), and so I’m finished with it. My vision continues good — better than 20/20 — and there are no complications. I’m still getting some eyestrain from sustained reading, which means taking regular breaks (which is advisable for all sorts of reasons), and when I’m tired my asymmetric vision is a bit unpredictable, but overall things are going fine. As I mentioned before, the biggest issue is driving in twilight or darkness – DON’T.
On Saturday I’ll start on two of the eye drops — the antibiotic Vigamox and anti-inflammatory Nevanac — in my left eye, three times a day. Kate will drive me in to the Surgecenter (such a clumsy name!) on Tuesday at 7am, and I should be home by lunch.
This morning I was belatedly going through the materials I’d brought home from the Surgecenter, and found a laminated card and a booklet. The latter was the “Product Information” for the synthetic lens. It advised me (in tiny print) that I should keep the card and show it to any eye doctor that I encounter in the future. (What, no micro-RFID tag embedded in the lens?) Reading the booklet reminded me of one of the things that has impressed me about all of this. The surgical techniques are wonderful, and I’m very grateful for the skill of my ophthalmologist, and the way this procedure has been made simple and painless. However all of this medical wizardry would be nothing without the extraordinary materials science that has gone into the creation of the lens. Think about it: a clear, plastic lens, with carefully calibrated UV filtering, refractive index and curvature, designed to remain crystal clear for many years, and capable of being rolled up so that it can be inserted through a 4mm incision and allowed to unroll into place. It’s an acrylate/methacrylate copolymer; the lens is 6mm across, and the diameter across the “legs” is 13mm. That’s impressive….
Wall Street and even some Apple fanbois were disappointed that Apple chose to release a minor upgrade to the iPhone 4 rather than a kick-ass, “this changes everything” iPhone 5. But I was delighted. Let me explain.
A few months ago, I decided to see what life was like on the other side of the “garden wall“, and I replaced my iPhone 4 with a Samsung Infuse 4G. Thin, big gorgeous screen, powerful CPU, bags of memory, the latest Android OS, and “4G networking” (whatever AT&T meant by that – certainly not LTE): I was determined to test “the best of the rest”.
Unfortunately, it has not been a great experience. The startup logo from AT&T exhorts me to “Rethink Possible”, and I have done so: I realize that it is possible that someone could create a crap product and try to compete with Apple.
What came I say about this puppy? (This is not a compliment: I’m not a dog person.) The battery life sucks. I’m lucky to get through 8 hours before the warning messages start appearing. OK, I’m syncing both IMAP and Exchange email in the background, but I’m usually in range of a WiFi AP. Often, I’ll take the phone out of my belt holster and it will be hot, as though it’s been running some CPU-intensive app, but Task Manager shows nothing running. Even so, the power just melts away. I’ve tried many of the apps that have been created to deal with this weakness of Android (and that should tell you something right there!), but nothing helps.
So of course I charge it whenever I get the chance, and at night I put it in a cradle next to my bed, with an alarm set. Unfortunately the phone insists on waking up, beeping, and turning on the screen when recharging is complete – usually at 3AM. This does not endear it to me or my loved ones.
There are lots of other annoying glitches, some of which are still mysterious. There is some package – not an app: no apps are running – which will occasionally vibrate the phone. If I power cycle the phone, it goes away. Because I receive corporate email on the phone, I’ve configured it to require a passcode to unlock it. However whether I have to unlock or simply swipe seems totally random.
But the most infuriating problem is the random hangs. I get one or two a week, and I usually have to power-cycle the phone by holding down the power button. Sometimes that doesn’t work, and I have to resort to sliding off the back case and popping out the battery. This evening, I encountered a new problem. I was riding on the Green Line under Boston streets; I fired up the Amazon Kindle app, and everything froze. I power-cycled the phone, and when it came back most of my apps were unavailable. Touching the generic icon produced the bizarre message that the app was not installed. Eventually I left the subway system, powered the phone off and on, and everything came up OK. From browsing similar accounts on the web, it looks as if Android needs to sync with MarketPlace on powerup. This is, obviously, absurd.
Yesterday I was just about ready to give up on this piece of crap, buy a new iPhone 5, and swallow my pride (and the penalty for early upgrade). But Apple came to my rescue by releasing the iPhone 4S, which is not quite compelling enough to make me switch back. Yet. So I’ll wait until I’m eligible for a penalty-free upgrade in January, 2013 (sigh!), or whenever the iPhone 5 actually appears. Thank you, Apple!
We went out to dinner this evening, and by the time we drove home it was twilight and all the cars had their headlights on. And that really sucked: my myopic left eye was overwhelmed with glare from every light source, and it really interfered with the image from my “new” eye. I reduced the problem by closing my left eye whenever possible, but of course my depth perception instantly disappeared.
So I think I’m going to have to minimize night-time driving until after my second operation. Bummer.
Herewith an update on the progress of my lens replacement procedures. It’s now six days since the procedure; this time last week I was enjoying a last glass of wine before going “nil by mouth”, knowing that I’d be alcohol-free for a couple of days after the procedure.
Things continue to go well. I had another follow-up visit today: my intraocular pressure is still up a bit (currently 25, expected value 21 or lower), but my doctor is unperturbed by this. My new eye still tests at 20/20; I rattled off the tests easily, and suggested that we should perhaps test at 20/15…. My final checkup for the right eye will be on October 11, and we’ll do the prep for the next procedure at that appointment. Then I’ll have my left eye done on October 18.
Over the last week I’ve been focussed on five issues: glasses, driving, protecting the eye, working, and eye drops. The glasses have been the most frustrating. I’ve been ignoring the “old eye” and concentrating on making things work for the new, far-sighted eye, and I knew that I would need reading (and computer) glasses. Eventually (in November) I’ll get prescription lenses, probably progressive, but for now I’m stuck with off-the-shelf glasses from my local pharmacy. Ostensibly, these come in a variety of strengths; in practice, I’ve found the descriptions to be useless. I’ve tried dozens of reading glasses, and bought four different pairs, but I’m not really happy with any of them. One thing that I forgot (basic optics – doh!) is that reading glasses are convex, and convex tends to mean chromatic aberration and barrel distortion. So all of my reading glasses have various degrees of chromatic distortion, and straight lines simply aren’t. Sigh. On the other hand, I have finally bought myself some decent aviator-style sunglasses, which are exquisitely comfortable. For the first time in my life, I have the sunglasses I want.
Driving has been OK, but it requires some care. I started driving on Sunday, without any corrective lenses (except for sunglasses). I discovered that I tend to augment my situational awareness with a lot of quick glances in the left and right side mirrors, without moving my head. This means that left side mirror checks involve just my left eye. But that’s the old eye, which is currently uncorrected. Oops. So now, I have to deliberately move my head to check my mirrors, just like I had to do when I was taking my Massachusetts driving test in 1981. Apart from that, things work OK. My brain tends to use the clear image from my right eye, but to supply some limited depth perception from my fuzzy left eye. The biggest problem is that my commute is the wrong way; in the morning and in the evening I find myself driving into the sun, low on the horizon, and even with decent sunglasses my “new eye” gets overloaded, which results in my left eye taking over.
Protecting the eye. Well, yes: I have to. (Remember those videos: this procedure uses a suture-less incision.) So I bought swimmer’s goggles to protect my eyes in the shower. I hadn’t realized that they were seasonal items; I had to go to a hiking goods store to find some. And I’m supposed to sleep with an aluminium shield over my eye, so that I don’t rub it in my sleep. On Saturday I took a nap, and woke up in a panic when I realized that I was rubbing my unshielded eye. Since then I’ve been obsessively careful about using the shield, taping it down so tightly that I now have a bruise on the side of my nose where it rubs.
Working. Sigh. This has been a pain. The simple fact is that if I read (and write) on paper or screen for more than 20-30 minutes, I get eye-strain and a headache. (I feel one coming one right now, as I write this blog piece.) This is really inconvenient in my line of work. All I can do is pace myself, and crave indulgence from my colleagues.
And finally, my life is dominated by those bloody eye-drops. Three times a day (I’ve settled on 8am, 3pm and 11pm), three different drops (Nevanac, Vigamox, Durezol), five minutes apart. And the instructions are to continue until the bottles are empty, so I have no idea how long it’s going on for.
But setting all that aside… today, after my doctor’s appointment, we stopped at Starbucks and sat outside with our coffee, and I marvelled at the clarity and delicate colour of the trees lining El Camino Real, seeing them with – literally – fresh eyes. It was wonderful.
Yesterday morning I had the first of two operations to replace the cataract-ridden lenses of my eyes with synthetic replacements. Everything went smoothly, and I now have 20/20 distance vision in my right eye.
We got to the surgery center at 6:15am,and the worst part of the morning – having an IV inserted less smoothly than usual – was soon over. I’m used to having eye drops to dilate my eyes for examinations, but for the operation we went a bit further. After the usual drops, the nurse placed a tiny drug-soaked sponge (about the size of a grain of rice) under my eyelid, and taped my eyes shut for 20 minutes. The result was suitably impressive. (Iris? What iris?) I spoke briefly to the anesthesiologist, who had previously handled one of my kidney stone treatments, and then I was whisked off to the operating room.
Although I was awake for the procedure, I don’t remember many details. The staff spoke very little, so I couldn’t even cue off their interactions. It seemed to go very much the same as the videos that I linked to in my previous blog piece on the subject. From my side of the eyeball, it was a spectacular light show: mostly pulsating yellows, reds, and cyans, with occasional periods of intense blue and green. There was no discomfort at all. And suddenly I found myself being wheeled into the recovery room, and given a drink of apple juice.
The following morning, I was back at the doctor’s for a post-op check. The pressure in my eye was slightly elevated, which is not unusual, and the doctor applied some eye drops to help to reduce it. As for reading the eye chart, I rattled off the 20/20 line with little difficulty. So now I simply have to keep taking the eye drops until all three bottles are finished, protect the eye against water and rubbing (I sleep with a shield taped over the eye), and show up for another check-up next week. And then in October, after I get back from the OpenStack summit in Boston, we’ll go through the whole procedure again for the left eye.
So what’s it like? Well, the clarity is amazing. I spent most of yesterday with my left eye taped shut, so I could concentrate on the new lens. (I keep wanting to call it my “new eye”.) Things are in focus down to about two feet; closer than that I need reading glasses. I’ve tried a couple of different strengths from the local pharmacy, but I still haven’t got used to them.
Without the clouding of the cataracts, everything looks much brighter, cleaner, and less yellow. At first it was quite amazing, particularly as I tried blocking first one eye and then the other. A chair which I had always thought was olive green now appears simply grey, while a wall that I had seen as cream-colored is now bone-white. However 36 hours later I’m starting to take the brightness and color shift for granted. (This may also be due to the return of my eye to its usual size.)
With my “old eye” patched, I obviously lost depth perception, so I’ve been trying to work with both eyes open. At distance, or when watching TV, my brain seems to take the clear image from my right eye and ignore the fuzzy data from my left, although I do get some slight sensation of depth. Reading or working with the computer is tougher. I use a pair of reading glasses, but the visual sensations are quite inconsistent as I move my eyes across the screen or from the screen to the keyboard. It’s quite a strain, and I can’t do it for long without getting a headache; if that doesn’t improve, I may have to revert to an eye-patch. Obviously I’m not going to be driving for a couple of days, but on Sunday I hope to be back behind the wheel. I’ll let you know how that goes.
Perhaps the biggest change, and one that I didn’t anticipate, is the result of a lifetime of myopia. Ever since I was a very small boy, when anything was visually unclear, or required careful attention, my instinct has been to bring it close to my eyes. If I was trying to disentangle a knot, or thread a needle, I would remove my glasses and peer at the object as close as possible. Suddenly, my world has been turned upside down: the closer I bring things, the less clearly I can see them. For some reason, this simple inversion affected me quite profoundly.
Overall, I’m simply delighted. The next couple of weeks, with one “new” and one “old” eye, are going to be a bit weird, but I don’t anticipate any problems. And I can’t wait for the next operation….
So I’ve started the countdown to my first cataract surgery. I wasn’t going to blog much about this, but I’ve found that although the web is full of text and video links for cataract surgery (in humans and other animals!), most are commercial or professional pieces. There seem to be relatively few first-person accounts of what it’s like to experience lens replacement. And since it’s a really cool technical fix, it’s worthy of the “Geek” tag.
I’m having my right eye operated on this Wednesday, September 21; the left eye will be done on October 18. In preparation for the surgery, I’ve just started eye drops three times a day: Vigamox (an antibiotic) and Nevanac (an anti-inflammatory). The pre-op tests took place on September 6, when they measured the interior and exterior geometry of my eyes using an ultrasound device; they’ll use these numbers to choose the right lenses for my replacements.
In peparation for the experience, I’ve been reading up on the subject and watching a number of videos. The best (lengthy) discussion of the subject is this lecture from UCSF:
For a quick presentation of the actual procedure, this video is good, though rather low-res:
One of the things I’m particularly intrigued by is how much difference I will experience in my vision. Yes, I know that my eyesight has been getting increasingly poor – my right eye is around 20/80 – but the deterioration has been gradual enough that I probably didn’t notice the changes. I’m really curious about how my color perception will shift. In some areas I’ve noticed the changes – increased glare during night driving, for instance – and I’m looking forward to improvements there. I just read an interesting piece by an ophthalmologist who himself had to have cataract surgery; as you might imagine, he was keen to document the experience carefully. (And it changed his professional outlook completely.)
Anyway, more and more of you will be going through this process over the next few years, so I’ll try to blog regularly about what it’s like.
The amazing thing about this crisis is the extent to which suffering and responsibility are completely out of proportion with one another. If you think about the people who are really suffering in the developed world today, none of them were executives at major banks, none of them were politicians involved in the construction of the euro, none of them were senior financial policymakers in any government, etc.
