I am the other guy working on Understudy. The iPad has been the best platform for Understudy so far, but I still have my fingers crossed that Apple builds a better touch screen into their next iPad. Who should I pray to for that wish?
They don't need to build a better touch screen... they just need to add wacom or ntrig digitizer layer with a stylus. Think: Macbook Air with a flip or detachable screen and wacom baked in. This would probably vaporize the iPad as the duality of fully tablet and fully laptop negates the need for both. I like my MBP, but I am seriously considering a Surface Pro so I can get the tablet form factor and a full PC in one. The added bonus is handwritten notes and practicing digital art which used to require a Cintiq or another peripheral device.
