I mostly want to email and surf the Web.
You can do those things on a tablet, but if you're more comfortable with a keyboard, you want a Chromebook.

A top model is the sleek Dell Chromebook 13, which has a full HD touchscreen, lots of ports, impressively loud speakers, and a robust 12-hour battery life. [From $399; dell.com]
