I'm going off to uni this September, and I know I'm going to get one of the new 13" MacBooks. At the moment I have a horrible windows desktop machine which takes up way too much space, and I'd love to get rid of it. I'm wondering whether to get the MacBook now or wait until September? Basically my only reason not to buy now, is that Apple may release a new line of 13" MacBooks (with built-in batteries etc) between now and September. How likely is this? Would I be better to wait? Cheers!
