Hello everyone! I have a macbook pro SR - 2.2 ghz 8600gt (128 mb) 4 gig of ram that I bought roughly 3 years ago. I'm going to law school next semester and am concerned with reliability. I have already had to have applecare replace most of the components over the years, but atm it seems stable. How reliable are these machines after 3 years? Would you guys recommend getting a new macbook pro, or do you think the one I have now will last at least another year? While I suppose I'd benefit from the extra power slightly, the most I usually do is word + itunes +ical + mail + 20+ tabs in safari + ~20 pdfs open on a bad day...usually eats up about all 4 gigs of ram but not too CPU/GPU intensive. Expose lags a lot though by that point lol...prob not enough vram. I also plug the laptop into a 24" monitor (LG 246WP). Thanks!
