I'm 16, and currently a junior in high school. I'm planning on buying a mac because I got this new responsibility that requires me to travel between cities quite a bit and organize files and stuff like that, and I heard macs last a long, long time. I don't know whether I should get it now (because of the whole free shipping thing and the price for the amount of RAM that comes default in it is to me, sorta ridiculous) or wait for the rumored new mac next year. It'd kinda suck to get one now and then have the new one come out in a few days, even if, I heard, it won't be too much of an upgrade for the 13" models. So I was wondering - if you take good care of your mac, how about how long can it last? If I bought one now, would I be able to use it in college? I'm graduating in 2011. And to that, what are some tips for taking care of it? Thanks guys.
