Apple has some cool guided tours (intro videos) for iPad. (They are slow to load for me now, though. For you too? This is very unusual for Apple, perhaps that page has been "slashdotted" or something.)
For instance, I learned that in Safari, if one adds a bookmark, one can choose to add it as an icon on the Home Screen (the main screen on the iPad, where all the app icons are), if it's one you need often. Neato.
By the way, have you noticed that the virtual keyboard on the pad has the little notches under the F and J keys that are traditional, so you can feel them with your forefingers? That's funny.
