So I just got my new Eee PC 1000H and it's obviously not a beast of a machine, but it gets the job done with most tasks. I'm looking for a lightweight IDE or text editor (read: lightweight doesn't mean lack of features, just that it's not a bloated piece of crap) The computer itself has a 1.6ghz Atom processor and 1GB of RAM. It's for school if that makes a difference.
There aren't any requirements besides that, I'm just looking for some suggestions on software that could be useful for someone in my situation.
