Since getting a MacBook Pro, My need for Windows has become less and less... I do have BootCamp on my machine for XP is there if I need it, but I've not booted it to it in for six months... Last I did was to play Oblivion... Since 99% of what I use my machines for now is Music Production OSX makes a lot more sense than Windows.
Certainly the ablilty of OSX to aggrigate devices and not crash/stutter (The CoreAudio seems to run RealTime!) under stress make it vastly superior to the nightmares that Windows gave me.
I apreaciate the comments that Mac's are for Retards... but I actually happen to like a Unix box that just works, each to their own I guess.
All intel Macs actually have two mouse buttons... The MB/MBP uses a multitouch mouse pad which is vastly superior to two buttons... You have to try it!
