Looks like a lot of people have been having trouble with over the sensitive tap-to-click function of the Asus EEE PC's touchpads when using Ubuntu-EEE. I was too, until I stumbled across this article which explains precisely how to disable tap-to-click by enabling the elantech driver. The article is so low in pagerank that you can't find it by googling for the problem.

I code a lot and also write some blogs, during writing sometimes my thumb or palm touches the touchpad and results in mouse pointer moving to another window or at a different place within the same window. While coding in "vi" editor in konsole, sometimes I have even accidentally closed the konsole terminal resulting in me loosing all the unsaved work.
