I used to use a 21UX for photoshop retouching and a little personal painting. I have been using an Intuos for more than 10-12 years at that point and I just couldnt get over the fact that my hand was in the way! As soon as they come up with invisible hands, I'll buy a nice big Cintiq.
I use a 21 at work and just ordered myself a 21 that will be with me in a few weeks. To me, it's seriously a life changer. I find it hard to go back to using 'just' a tablet. I don't really notice the lag most people complain about, either because I use lazymouse a bunch or because I would rather that than the disconnect…
