thanks for the replies guys, i knew this would be argument bait when i started so im not surprised lol
for the people who suggested ubuntu, i have tried it (dual booted my current pc) and it was alright for a while, but it got annoying when various problems started popping up (sound not working in youtube and the like).
as for audio engineering on the mac, i know that there are a heap of industry standard programs out there for mac, ProTools being one of them.
my drum teacher uses Logic Studio and it produces some pretty good quality recording, i'll only really be using it for demoing my band anyway, for an actual album, we'll go to a studio and get it done properly
as for cash, that shouldnt be a problem anymore, i've made a deal with my parents that if i get an OP score (the annoyingly complicated high-school exit grade system we have in queensland) of between 1 and 10, they will buy the laptop for me.
i think i will go with a mac, just cause i'm beginning to dislike windows (maybe thats just because my current pc is woeful, i dont know), but i've pretty much fallen in love with the 2009 MacBook Pro models, so i may get one of those. and anyway, no matter what, i still plan on dual booting with windows xp, so i always have that option
again, thanks for the replies
