My next laptop: a tough choice

I few weeks ago I started work at Vyatta, which had been recently acquired by Brocade. On my first day, I was handed a Brocade corporate laptop. It’s a Dell: 13″ screen, 4GB, 128GB SSD, Windows 7. As corporate laptops go, it’s perfectly nice, but I’ve been a Mac user for many years now, and Windows Just. Feels. Wrong. The first time I tried to send a reply to a meeting invitation in Outlook and found that I couldn’t navigate back to look at another email message, I realized that (a) Outlook still had many of the bugs we first encountered 15 years ago, and (b) I was damned if I was going to use that crap to run my work.
As I wandered around Vyatta and Brocade, I noticed many MacBooks in use. Apparently many others felt the same way that I did. As an experiment, I configured my personal MacBook Air as a work machine – (guest) wireless network, Exchange, Lync for IM, Office, etc. – and apart from a few corporate functions it all seemed to work just fine. However, as a matter of policy I don’t want to mix work and personal stuff – certificates, passwords, email, browser settings – on one machine. So I’m planning to go out and get myself a MacBook for dedicated work use, and I would like some help in making the choice. (And yes, I’ll keep the Dell laptop, chained to my desk, for those occasions when I need to log in to Oracle or other corporate systems.)
Weight is important. Today I love my 11-inch MacBook Air: it’s as light as a feather. On the other hand, putting together a complicated PowerPoint or Keynote presentation is challenging on such a small screen. And power is also important: I want enough RAM and CPU to run DevStack or CloudStack under VirtualBox. And of course I don’t want to spend too much…
So the choices seem to be:

  • MacBook Air: 13-inch screen, 2.0GHz Dual Core i7, 8GB RAM, 256GB SSD, 2.96 lbs. – $1,599
  • MacBook Pro: 13-inch Retina screen, 2.9GHz Dual Core i7, 8GB RAM, 128GB SSD, 3.57 lbs. – $1,699
  • MacBook Pro: 15-inch Retina screen, 2.4GHz Quad Core i7, 8GB RAM, 256GB SSD, 4.46 lbs. – $2,199

There are pros and cons for each. Reviews are all over the map. Thoughts?
