I've tried this idea with the n810 and bluemaemo, but it seems to not work as well as I would hope, since the right mouse button is not constantly 'clicked'/held down when you try to draw/write on the screen (I actually tried to use it with Vista's handwriting feature). If you do use the button to click and hold the right mouse button, you can't just lift your stylus and write/draw somewhere else. You have to click the button again and click the button once more for when you want to resume writing/drawing somewhere else. This makes it a very unnatural experience and therefore defeats the purpose of using the n810/n900 as a stylus on a touch screen. For anyone that has tried this, is there something I am missing?
