Here's my situation. I have a maxed out 12" PB that I've had for about a month. It does what I need it to, but I still manage to run it hard enough to get beach balls, etc. I also find the screen space pretty small when I'm on the road. The warranty is up soon, and I'm debating between spending the money on the applecare or selling the 12" and upgrading to a 15" I figure the 15" will cost about $1700 with 1.5gb of ram (newest revision with a full warranty). I don't want an MBP because the glitches scare me and because most of my time is spent on CS which won't be available for a while. I figured whatever I do, I'll upgrade in about a year or so. So do I spend the $250 (edu discount) on applecare or spend the cash to upgrade to the 15"?
