Even with a mouse it's bad. If you have a free spinning scroll wheel scrolling a little can cause huge jump, but once you start scrolling faster the page will do opposite and not scroll at all (probably some kind of mechanism trying to prevent skipping over multiple pages). The fake scrollbar can't be used either and menu bar is useless because because who knows what each two letter pair means.
