There are actually two problems keeping us from writing on such devices: lag and temporal resolution. Many touch sensitive input devices have a too low temporal resolution such that movements at the speed typical for handwriting cannot be captured in sufficient detail. I agree that the lag of this noteslate thing is a problem but at least the temporal resolution seems pretty decent.
