Couldn't the paper feel be solved by a simple screen overlay on an iPad? Something thin enough to give the texture? Almost like an anti-glare screen protector.

I'll admit, the pencil on glass just doesn't feel right. I'd rather some perceptible drag/friction. It also helps me reduce errors as my drawing and writing styles are abysmal so I need something to keep some traction.
