I had problems with the spacebar of my eee; I ended up following the advice on http://forum.eeeuser.com/ and detached the space key, and thickened the raised part that activates the switch (I think they suggested glue; I just used some layers of sticky tape. Still working perfectly after a year of heavy use). I think I ended up doing something for some other keys; I also disabled caps lock (I'd press it instead of tab). BTW I use vim all the time.

It was annoying, but the hacking was fun.
