My laptop is close to kicking the bucket and I'm thinking about picking up a tablet. Is there a decent tablet out there that is good for college students. I'm only looking for wi-fi, microsoft office, and a usb port or two. I'm not looking for fancy apps, games or 3G. Tablets are very portable and I would prefer to pick one up over a laptop. I know this may be a stretch but is there anything out there for under $450?
