I recently purchased my tablet (Asus EEpad transformer, 10.1 inch), and quickly grabbed Photoshop Touch and a bamboo pocket stylus, after a few weeks of research on each.
The last component, my stylus, arrived yesterday, and Photoshop Touch does not register the pressure from it at all. I have gone in to the brushs>sensitivity area and tried both opacity and size. I have also gone to settings>stylus, and there is nothing other than the two slide bars. How do I get the little window that allows Photoshop touch to pick up on my pen?
I don't think the Eee Pad had pressure sensitivity, did it? One of the only tablets I can think of with pressure-sensitive support out of the top of my head is Samsung's Galaxy Note 10.1. (I think Lenovo's Thinkpad is the other one.)
Otherwise, you can use a capacitive stylus; you just won't have pressure-sensitivity.
It must, because it works with the free drawing app I downloaded (don't remember name, am at work and away from the tablet). I would like to use it with my photoshop touch though, both since I spent money on it and because the free app tends toward very shakey lines.
