Android has pretty good mouse and keyboard support already. Try one of the Asus Transformers in laptop mode, for instance. Keyboard shortcuts, mouse cursor, two-finger scrolling, all works as you would expect on a desktop.
High-resolution apps are still somewhat lacking because the larger tablets haven't sold that well, but I hope this will improve.
Honestly, if Android came on top of or with a real Linux base so that I could be assured my existing Linux applications and command-line environment will work... I would totally switch.
The new Ubuntu for Android project will take over the world.
