I recently got an iPad and the first two things I bought were Sketchbook Pro and Brushes from the app store. I like things about both (Brushes seems to have a higher rez) and dislike things about both (no way to change brush size in Brushes without stopping, opening a sub menu and moving the slider). It's a great virtual sketchpad but it won't replace photoshop any time soon. Or maybe it will. I dunno, what am I , Nostradamus?
