There is one huge problem with iPad styluses: the rubber tips tend to drag or even stick on the screen, especially when the screen gets greasy (which is always). Some styluses are better than others: The Wacom Bamboo manages to glide right up until Peak Filth, and the latest Alupen Pro comes with instructions to never touch the tip with your fingers (as you’d expect, I touched it immediately and often after reading that).
But the TruGlide Stylus takes a different take altogether: it ditches the rubber and replaces it with something that looks like a tiny metal scouring pad. Only it doesn’t scour — it glides.
