Apple's iPad Video Walkthroughs
Apple has posted a number of videos that walk through each of the default apps for the iPad (via Macstories). They are worth a watch. Being able to see the iPad in action reveals a number of little details.
A nice touch in Safari, when you tap the location bar to start typing, a bookmark bar (like in desktop Safari) pulls down.
The Safari video also answers one question I had long wondered. It looks like you'll be able to watch embedded videos inline without having it pop open the YouTube application. I've always found that flow on the iPhone really disorienting.
Watching the video on Keynote really makes it clear that using a keyboard and mouse to do any type of design work is going to feel incredibly antiquated in the very near future.
I cannot wait to get my hands on one Saturday.
Side note: The icon the iPad displays on screen when you lock the rotation (shown in the iBooks video) looks awfully familiar. I know, but it's fun to pretend they did ;)
