get a tablet and a wireless keyboard. Maybe a nexus 7. That way youcan be portable and type up stuff when you need to. Plus you could write notes on it, though. Some people like to do that on their tablet. (I usually don't) . The nexus 7 is a small tablet granted but it's powerful, built well and if you don't mind spending the time figuring it out, probaby producted. Plus wouldn't you like to have 8 hours of battery vs the 1.5 hours you'll get on a cheap laptop?

just a thought.
