Here's my actual out-of-the-box experience with the iPad:
My iPad arrived Apr 3 morning as promised, a Saturday. Sadly I wasn't in the office yet, so I had only a UPS "we missed you" sticker to play with all weekend.
Monday when I went into the office I opened the box, but it only showed the "Please sync me with iTunes" screen. It was cool that when you turned the iPad the diagram swiveled, but I couldn't show it off much to my coworkers.
When I finally got it home to sync with my iTunes, it didn't recognize it (nothing showed up in the iTunes window). Since iTunes has been nagging me to upgrade from 9.0 to 9.1, I did it (which took 30 minutes, required several password entries and a reboot) and it worked.
I wasn't sure if I should restore my iPhone's configuration onto it, or set it up as a new device. I opted for new. It cranked away, downloading videos & apps for about 3 hours. I think the time was mostly generating small version of my 12000 photo collection.
The next day I got to play with it, and it was lots of fun. But it wasn't the usual Apple out-of-box experience. I'd like to get iPads for my kids, but I worry they'll have a lot of trouble setting it up.
