I use a MBP at home, because there's nothing within a light-year of Lightroom (or Aperture, which is pretty much an equivalent package) for RAW photo workflow.

I use a MBP at home, because there's nothing within a light-year of Lightroom (or Aperture, which is pretty much an equivalent package) for RAW photo workflow. If it weren't for that single piece of software, I could switch to Ubuntu/Debian full-time and be quite happy. When I'm at work writing code, it's 98% Linux, with occasional compatibility testing on a Mac or Windows system. Apache, Vim, Ruby, and PostgreSQL all run just as well on Debian as they do on a Mac, and a lot of other packages work much, much better -- plus, they're just an 'apt-get' away.
