next macbook update should be around october or november. the specs that you get on a mac are nothing compared to the price/spec ratio on pcs. take a look at some HP computers for metal finish. though you won't be able to use logic. then again there are plenty of programs you'll be able to use.
i've had a mac mini for over 4 years. ran pretty well, till last week. then the motherboard broke. piece of shit. the cd player stopped working a year ago.
macs look good, but there is a reason people call them crackbooks

i guess i'm just venting. but from collecting other first hand accounts of mac owners, i think mac simply doesn't care about the build quality of their machines.
