getting a mac

[soundtest]

ok so my pc desktop is a piece of shit, and rather than upgrade it, i've decided i'm going to ditch it and get a mac. i've been using linux for almost a year now, so i may install linux on the mac, but if i go the OSX route i'm gonna need software... and paying for software goes against my belief system.

pc warez are simple enough to find, but does anybody know of any good sites to find mac warez/appz (especially audio/midi production)? also, i'm somewhat new to OSX and macs (i've used them a lot at work, but i've never really had my own where i could do whatever i wanted to with it) so any advice from mac users on how to tweak the system, cool programs to look out for, etc. would be greatly appreciated.

also, i'm assuming the hard disk can be partitioned - can you dual boot on a mac?
