With the new ones just around the corner, I'm being offered a black 13 inch DualCore MacBook with 2Gigs of RAM for 600$. It's about a year or two old. Good deal?! Bad deal?! What are the rumored prices for the new ones?! If I can get in 4 weeks a better one for 800$ the deal would suck but if it's about the same for 900-1000$, the deal is slowly getting better. What do you guys think?
