As I said, I think subpixel precision is much more important than pressure sensitivity. Can you really produce readable handwriting with XInput turned off? If so, I would love to see an example. That said, I am all for Xournal on Android! I also tried to learn about Android development and wrote a small text editor<http://www.inkcode.net/qute-android> as an example. I had high hopes for the HTC Flyer, but I did not get round to buying one yet. Also, I tried to find the HTC pen API documentation, but failed. If you could post a link, I would be very greatful.
