This post has the most useful iPad (~7-minute) video/demo I’ve come across so far (it also includes the brief list of initial thoughts/impressions I referenced last night, e.g., re lack of multitasking). Apple has also posted the (~1.5 hour) intro video here, but you have to use Quicktime to view it (I suspect it will be transcoded and posted on YouTube soon).
Here it is folks, the Apple iPad. The screen is gorgeous, tilting is responsive, and the thing is super thin. Still, if you've used the iPhone before -- and you can see the two devices side-by-side here -- there's not a lot of surprises here so far.
