I'm not very technical on computers and laptops, so please excuse me. I'm a college student studying Business and Economics. I currently have the old white MacBook from 2007. It's getting slow, and the battery just died on me. I have to keep it plugged in for it stay on. I'm going to get a new laptop soon, maybe during the holidays, but don't know whether to get the MBA or the Pro. I know they're almost the same price (13"), but is weight and portability of the Air better than the PRO? I surf the web a lot, and I hardly ever turn off my laptop, only on weekends. I use Word, Excel, and Powerpoint a lot, and that's about it. The missing CD drive isn't that important to me. And also, does the AIR have a hard-drive? I really don't know what Flash is. Anyways, thanks in advance.
