I use a touch screen laptop. the screen flips around and folds down over the keyboard so it faces up and the whole computer can be held like a pad paper, or you can flip it round and set it up in tent shape with the screen facing you like an easel. I draw into it with the included stylus, although I could paint with my fingers if the app allowed. I can rotate the screen display to landscape or portrait in any direction too, to suit whatever I'm doing, or just use it like a laptop.
Touchscreen tablet PCs are more expensive than compatible laptops and a bit heavier because the screen is fronted with glass instead of scratchable plastic. I love it. this is my second tablet pc and I'll never go back!
If I had a wacom tablet I'd still need decent hand-eye co-ordination but this is exactly like drawing on paper.
Using HP touchsmart tx2 1020ao tablet laptop with stylus and multitouch screen. I love being able to draw right onto my computer! Now if Art Rage had a "fingerpaint" mode I'd really be playing!
