I think it's great to post information about other devices here. The kind of people who frequent this forum includes many "early adopters" who want to know whats out there.

I am intrigued by the Motion device you reported on. It looks pretty good, although the base model comes with an anemic 1GB of RAM, which I highly recommend against, as Win 7 will run very poorly. The price is right on, and they make great devices. I will probably buy one when they come out.

Another device was recently revealed by Fujitsu, here

This device comes with 2GB RAM in the base model and seems to be cheaper than the Motion device, though probably not nearly as physically rugged.

Another Windows tablet is the one from Onkyo, and having played with it in the stire, it is way too slow to be useful.

Rounding out what I know about Win 7 tablets is the ASUS EP121, which was a great experience (in the store). Very fast processor and the more expensive model comnes with 4GB of RAM, making it a great machine. It is a little big at 12.1 inches and over a kg in weight.

One thing that makes a Win 7 tablet inviting is that it is very easy to develop for, given the long history of the platform. Developing for the iPad is not so easy, especially if one wants to develop a specialty "in house" app.
