I am already using the last revison of 12" Powerbook G4 with maxed out ram, and it isn't quite cutting it any more, I need some more power for aperture and adobe. Here are my circumstances: I am a college student I use my Powerbook as a desktop 90% of the time - External monitor, keyboard, and mouse. I just feel more comfortable working at a desk. However, I do find the portability useful when I do need it for school projects and taking it to the library and such. I will most likely be studying abroad next year, so a desktop will not be a possiblity next year. It will mainly be used for aperture and adobe products with perhaps a little bit of music production in the middle. I'm thinking that after I sell my PC, Powerbook, and other stuff, I should have about $1900-$2300 as a low estimate based on current going prices, but would love to spend less. If I get a desktop, expandability won't really be an issue, because I will only have it for 10-12 months, so I am leaning towards buying an iMac (20" or 24") or a Mac Pro now, selling it and buying Macbook Pro for abroad, then see about what happens when I get back. What do you guys/gals think I should do? Should I upgrade? Does this sound like a good plan? What would hold its resale value better?
