Viewing angle issues are all a result of the type of panel. Apple touts having an IPS panel in the iPad but that's not really anything special.
As for the touch sensitivity issues, I didn't see any last Tuesday when users were playing with the demo device that was on hand.

I will say that the iPad has a definite advantage in the CPU, as ARM cores will continue to be significantly more efficient than the Atom for some time. But such is the price we pay for defying Jobs.
