I really want to get either a) an iPhone 4, or b) sell my MBP and get the newest model. Currently I still have my first ever MBP (late 2006, 2.16) and it seems like I've held onto this for far longer than what most people do -- it's coming on 5 years now! (Of course I have heard about the diehard Powermac G4 users still using theirs as well). I'm wondering how long I can expect my MBP to run for? I upgraded the HD last year, and while the battery unfortunately never holds more than 2 hours anymore (even after several replacements), and the fan get's loud as a s### a lot of the time, the computer still runs everything perfectly, and I could probably put it in a box and sell it as new since I have taken such good care of it. I'm just worried that one of these days it will just completely tank on me, which is why I'm trying to decide what to do.
