Well, jealous in a "I'd love to keep one in the box if I had a kid" way, and perhaps jealous because it would be cool to write some games on it.
Its a cool laptop regardless.
The OLPC keyboard is definitely smaller than a normal keyboard, the keys are about 50-60% the size of normal ones. I'm not sure on the EeePC key layout, as I've not seen one in person.
Ideally, the best form factor for a laptop I've ever used was a Thinkpad 365XD, although it could be made a little thinner. It was big enough to easily type on, but not so large that it was a PITA to stuff in a satchel or backpack.
