This is a pretty curious novelty toy from Wacom. It's one of those things you can either easily fit in your workflow or you cannot fit it at all.
Whereas I like the idea of being able to draw "anywhere" and on cheap paper, this is not something I'll be getting. I don't miss drawing on paper much at all compared to my tablet, and this (notably the lack of an undo when drawing) will essentially feel like a step back for me I think. If I really wanted to draw on paper I'd much prefer drawing like normal, then scanning.
It's a cool gadget, but if I was saving up for a new Wacom gadged I'd rather keep on saving for a cintiq than to get this. The new
Cintiq 24HD is on my wishlist now (not that I'll be able to afford it, but one can dream).
