This makes me wonder if the real reason there is not Balsamiq for iPad is because of the threat of rejection for "running" and "editing" Balsamiq markup models. I understand that Balsamiq is an Adobe AIR/Flash product, and it would have required a major port to CoreGraphics/Cocoa (since the CS5 compiler was banned because it leveled the mobile platform playing field by allowing near write-once, run any device).
