Korean maker UMID has released a MID whose product name is ... MID.

UMID MID MID

Though, it's a 1.1GHz Atom, so I expect it'd be an even bigger power hog than the 800MHz Atom based MIDs. And, unlike the other MIDs, I don't see a mention of a Linux variant.

It's a clamshell, so it's sort of like a Nokia E90. I think that'd be an interesting format for a Maemo device... (as I've said before, an updated E90 with both kinds of North American 3G (AT&T and T-Mobile), complete with full phone functionality, and Maemo, would be quite interesting to me) we'll see how the UMID MID MID does though.
