The iPad's display, like most Apple displays, is bright and brilliant. It runs a modified OS used for the iPhone, which means that it can run most of the iPhone apps as well. From the videos and demos, the touch screen response time is excellent, but I can't help cringing when I see all those unavoidable smudgy fingerprints on the screen.
And just like the iPhone, Flash can't be displayed on the iPad. Since Apple & Adobe seem to be at each other's throats regarding this issue, I don't think the problem with Flash will be solved any time soon.
But all shortcomings aside, the iPad is here to stay--I'm pretty sure this device will be greedily snapped up by a lot of people, even though they don't really know what's it for, and they don't sure as heck need it. I don't think I need one; I have a difficult time typing without tactile feedback, and Apple products are so damned expensive and overpriced here.
Of course, if someone gives me one...heh.
