I don't think the advice here is suitable for touchscreen devices. In those cases you might consider having a single button that, once clicked, will reveal additional functionality. On another note, it looks as though these guys guys have come up with a way to detect hovering for touchscreens: http://developer.practicalecommerce.com/articles/1900-Maybe-Touchscreens-Won-t-Kill-Hovering-After-All http://developer.practicalecommerce.com/articles/1900-Maybe-... Apparently it can detect the user's finger while actually hover above the surface of the screen.
