Think I found a stylus that:
(a) Cheep!
(b) Does work!
Targus - Stylus for Apple® iPad™ - AMM01US
It uses a sold rubber "point" and does not require you to drive it though the screen like others. Also is not like the conductive foam ones. And not that expensive.
The main item is that it just works!
This is a significant question, so I will be watching for the answer...Did anyone find a screen protector compatible with the Targus stylus?
But why isn't there one with a sharp enough point to write well with? is it because the capacitance would be too small?
