Touch devices have different semantics.  They simulate the
onmousedown/onmouseup events for backward compatibility, but
you really can't assume they will work the same way.

For example, how would you scroll a webview if it replied to the
initiation of every touch instantly?  The touch, stroke, lift
has come to be known as a scrolling gesture, and the web page
should not receive any onmousedown/onmouseup events.  If you
touch and lift without stroking, only then can the system know
you're not trying to scroll, and it offers the onmousedown/
onmouseup events at that time.
