In fairness though palm rejection is just as important as a stylus and I have yet to see it work reliably for me in any app I've tried. It would be better if the pen could actually communicate it's proximity to the screen and have it completely shut off touch input while it's near.
Exactly. There are quite a few stylii available for the iPad because there are people who need/want one. Not everyone wants to write with their finger, any more than everyone wants to type on a piece of glass.
(None of them are as advanced or as integrated as the HTC one, though.)
and 7" tablet = fail in my opinion (still can't fit it in your pocket, i like the bigger 9" screen for doing everything)
