My laptop appears to be on it's last legs and it looks like I'm going to need a new one soon. I've had mine for 5 years so it's a bit bulkier than I'd like.

I'm looking for a new one that's compact enough to make commuting with it a bit easier. It also has to be tough enough to stand up to the abuse of traveling.

Anyone have any suggestions? I don't really care about an ultra fast processor since I mainly use it for internet and email.
