I'll be a freshman in college this fall, and I'm looking to replace my current laptop (Dell Inspiron 1501) which is steadily dying. The trouble is, I'm not sure which model to buy. I'm not too savvy with computer specs and such. I'm hoping this laptop will last me through the 3-4 years of undergraduate. (Should I drop $349 on AppleCare? That's quite a hefty price tag; is it worth it?) Also, I plan on gaming quite often and I'm hoping to see an increase in performance speed and graphics from my current laptop, which shouldn't be too difficult considering its specs (2GB RAM, AMD Athlon 64 X2 Dual-Core Processor 1.7GHz, ATI Radeon Xpress). Is it likely the MacBook/Pro series will update within the time frame of the back-to-school promo? Should I wait until the last week before the promo is over, in case an update happens? The MBP 15" 2.66 looks quite attractive, but of course, I'd like to save money wherever possible. Will the 2.4 do? Is 2GB RAM enough? (The sluggishness of this laptop really frustrates me at times, but I'm not even entirely sure if this is related to the amount of RAM.) Also, should I buy any accompanying software? I realize MBP comes with OSX and iLife, but is iWork necessary? Worth paying for? I heard Macs are less susceptible to malware, etc. attacks. Does this eliminate the need to buy security software?
