I'm trading my MacBook Pro for an iMac because literally the only time my MacBook Pro leaves the apartment is when I take law school exams. I still need a laptop for law school exams, so I'm thinking I'll get a netbook for that. Is that a good idea? I'm looking at the Acer Aspire One, which is $350. I'm also eyeing the Dell Mini 9, which is also $350. My other option is a cheap Dell (full) laptop, which is $500. Any advice?
