The Vadem Clio (aka Sharp Tri Pad) is a three-pound pen-based Windows CE (WinCe/PocketPc) computer. It can be opened like a notebook, stood up like an easel, or laid flat like a pad. (See http://www.vadem.com for more info.)
It reminds me of the Momenta, except that it works. I'm wondering whether anyone has been working with Squeak on it.
