It would be important to know if an iPad can be as responsive as a wacom tablet. I think an iPad version of photoshop could work as a simple photo retouching app as shown in this demo. But it will be really, really hard for Adobe to get the same level of functionality into an iPad app that they currently have on the desktop. Can you imagine using the type tool, or manipulating a document with hundreds of layers and groups on a 10" screen? Seems difficult. That said, a fast tablet with video out to a bigger screen would be pretty amazing, actually: palettes and details on the tablet, image you're manipulating on the big screen. The iPad has a long way to come in equaling the speed of desktop, but you can almost see it down the road.
