Aaron Woodman, the director of consumer experiences for Microsoft's mobile division, was a guest on today's Engadget Show, and he had a nice surprise for everyone: a prototype of LG's Windows Phone 7 Series phone.

There's not a whole lot in the way of details—it's a slider that's a bit thicker than the iPhone, it has a 5MP camera, and sports six hardware buttons—but it's still exciting to see the new operating system on a branded device for the first time.

Woodman wouldn't confirm nor deny if Windows Phone 7 Series would support Mac OS, only mentioning that it was a topic the team was currently discussing. Hey, at least the notion hasn't been shut down out of hand, so we'll take this as a no news is good news type of thing for now.

Head over to Engadget for more pictures and a quick video clip of the LG phone in the round. [Engadget]
