This phone actually runs Windows 7 Home Premium

[Archean]

It's the world's smallest PC that fits into the palm of your hand, and it runs Windows 7. Not Windows Phone 7, but the actual 32-bit Japanese version of Windows 7 Home Premium (with SP1).

Cool who makes them/what make'n'model?

Its not surprising when you consider the clock speeds and GPU's are approaching that of budget PC systems.

It still looks very, very cool though!

The fact it withstands 2 hours usage is quite surprising as well. I'd have thought it would tax the battery considerably more.

I guess with the fact, that to my knowledge no other phone in the world operates a true blue O.S. like Windows 7, this utterly redefines the term "pocket P.C."!

Impressive, very impressive!
