I have a 15" Powerbook G4 with 1.33 GHz, Combo Drive, 512 MB RAM, 60 GB HD, 64 MB VRAM, its a Rev. C. I wanted to trade for a 12" with similar specs, a guy who lives near me offered his 12" Rev. C G4 with virtually the exact same specs (Combo Drive, 512MB RAM, 1.33 G4) the only difference is that I bought mine in January and he bought his a year ago (which means its out of warranty), he also offered 200-300 cash along with this trade, also he would be willing to drive a couple hours to where I live. Is this trade worth it, because I am a full-time student and need the portability, and the 15" is good but not good enough to carry around to all of my classes, I also only use my computer to listen to music, surf the internet and word process. I also am planning on purchase a 20" ACD with or without the trade. Thanks.
