Hey everyone-- I've got a painfully-obsolete 12" Powerbook (1.5 GHz G4, 1.5 GB) that I sense I'm outgrowing-- and desperately want a new machine. Here's the dilemma... I could replace the battery (second time) for $130 and be able to at least use it as a laptop, or just make the switch and try to sell it in its current state. I stress the HELL out of my machines-- photoshop, video, many programs open, watching streaming movies, etc. A lot of these things don't work so well on my machine, but I've used faster (non-uni mbp's) and loved it. Clearly it would be a lot nicer to have one!! My way of working definitely demands high performance, and I've made much of a machine that doesn't have a whole lot. Anyway... I am in my last term at college, in a programming class, so I'd qualify for the student ADC discount ($570 on the machine I'm looking at!). In 3 months I won't qualify anymore. BUT, in three months I will be going away and won't need my Mac at all for several weeks. (Obviously after that I will.) I really wanted to wait for Nehalem because it will be so much more future-proof (and I'm hoping it has the high-capacity battery, as well), but if I do that I will lose out on the discount and have to pay $130 now just to keep this machine running in a normal state (with all my photos, music, movies stuck on external drives... gahhh). What makes sense in this situation? Should I bite the bullet and just buy it now? Also: is the 2.93 vs 2.66 going to be significantly worth it if I can upgrade at the reduced price of $240?
