I switch between Macbook and Thinkpad/Ubuntu almost daily. Why? Because I get bored on either of them fairly quickly :-) I love both of them, but my vote goes towards Ubuntu/Linux (and I mainly code on ThinkPad) for three reasons: 1. Most hackers' software is native on Linux, although nearly all of it exists for OS X. But nothing beats Debian/Ubuntu's aptitude: nearly everything imaginable is a few keystrokes away: can installed and pre-configured in seconds. And guaranteed to "just work". 2. Apple's hardware is no match to IBM's. UltraNav combo kicks ass, and I feel crippled and slowed down when using a touchpad of other laptops, including Apple's. 3. Linux is more flexible. It's not the "sysadmin carp" that some people from the 90s complain about, it's genuine flexibility that comes with choice. There are many more different terminal apps, different ways to manage workspaces, various window management plug-ins, screensavers even! OS X is more commercialized. Besides, I dislike some of Apple's software. iTunes is number one on my hate-list. :-)
