I need a laptop for school. I originally needed one last August, but decided to wait until Macworld 2008 to see if they introduced a new laptop. The Macbook Air sucks, and I'm pretty set on a Macbook. But I don't know if I should get one now or wait another 3 months to see if they come out with a newer version. I really need a laptop now, but will be extremely pissed if they come out with a newer one in a few months. What should I do?
