So i've decided to purchase a new Macbook, mainly for school purposes. I've also convinced my mother to make the switch and dump her old Dell for a new Macbook. Only one problem, buy them now or wait for a real upgrade? For my purchase i'll be getting the base model since i have a mac pro to do any work that would require real power. Basically i'm just looking for portable word processing and email. I kinda wanna buy it now since they just got a small update, and then I'll get to use it all summer. I'm definitely buying it by September. My question is does anyone expect any major updates by then? Namely Santa Rosa or an even smaller size than 13.3 inch. As for my mothers purchase, I'm getting the feeling that she doesn't want to wait for an update. The choices available now would more than satisfy her needs. One more thing... for anyone who has purchased one of these new Macbooks, have there been any documented problems with them so far? Extreme heat, yellow color, fan problems... the usual?
