Just so others know, if you were thinking the new Adonit Jot Touch 4 would be backwards compatible with artrage for the ipad, it isn't. Only the original jot touch works. I got one just assuming it would be, at least the pressure sensitivity part, but didn't research enough. Jot4 Works with Zen Brush and SketchBook pro, but I didn't really care about those, though I'll probably be playing around with them a lot more now. Hopefully in an update sometime in the not too distant future? Please?
