I picked up a MacBook (black) in June of 06 after I graduated high school and it's been fine with a few faults. My screen flickers more frequently, battery life is starting to get worse, some heat/fan issues among a few other things but it hasn't really bothered me too much. My Apple Care ended back this past June so there isn't any way of getting it fixed/replaced without a fee. I'm going to start using Illustrator for cartography related projects and I'm going to end up dual booting to use a program called ArcGIS for future classes as well in addition to the usual MS office apps, eventually Logic (though GarageBand works just fine as of now), iMovie editing, and maybe even some light gaming. I'm debating between the mid-level 13" with an external monitor or just the base 15" and being done with it. For those of you out there who have upgraded from MacBooks (or similar) that are as old as mine or even older, was it worth it? Or should I just keep using my current MacBook until it dies?
