Well, for now it doesn't run photoshop, and if it ever will it will probably be a light version.
However, the iPad is cheaper than any of the cintiq tablets, it runs on a battery for 10h and it doesn't come with the bunch of wires the cintiq 12wx comes with. On top of that it can play your music, store your pictures, and run lots of other applications.
Even though Apple released its own paint application called 'Brushes', I would love to be able to use it with Photoshop/Painter too. I wonder if the iPad can be used as a normal tablet connected to a computer, cause in that case I'd want one.
What's your thought on the iPad?
