Better (and cheaper) buy proper wacom
If you already own an iPad, but not a pen tablet

I'd highly recommend this over a Wacom or similar. $20 compared to $500+ for a decent one.

There are a lot of curious artists or photo-processing folks wondering if they would do better editing with a pen on-a-screen. I've spent well over a grand figuring out it takes up too much space for me in a mobile setting. I still use it for specific tasks at the desk, but if I could figure that out for $20 I would have been ahead of the game. THEN if I loved it I could search for the pen tablet that meets my needs, and if not save a few hundred.
