I seem to be a verb

This nicely demonstrates two important differences to a laptop:

It's unbreakable: Did you fuck up? Are you lost or bored? Hit the only button on the device and you're back in a familiar screen instantly.

I'd feel uncomfortable seeing a kid as randomly click around on a desktop as this girl is hitting the touch screen – she might break something! Here there are fewer ways to accidentally delete stuff, no such thing as an unresponsive system with a busy cursor, etc.

It feels natural: Apart from the obvious touch screen and the lack of window management, the form factor plays a big role too: Turning the device this way and that, offering it to someone else ("Here, you try it!"), gathering around one to collaborate,... all that works much better than on what we're used to.

I'm convinced those two aspects will make this a much more enjoyable experience than the average computer for many, many people.
