Windows Phone makes the rounds at Mix (photos)

Microsoft had a few of the prototype Windows Phone 7 Series devices on display at its booth at the Mix10 conference in Las Vegas this week, but it wasn't letting attendees hold or touch them.

While conference goers didn't leave with one of the devices, Microsoft did release a free Windows-based emulator and tools for developers to start writing their Windows Phone apps.

No, it's not the iPad version of Windows Phone. Microsoft used this huge touch screen to show off the features of Windows Phone.

One of the Coding4Fun demos on display at Mix was a version of Risk that ran using Bing Maps as the background.

One of the most fun uses of Windows Phone in Monday's keynote speech was when the phone was used to control a T-shirt-launching robot that fired red polo shirts into the crowd.

Clint Rutkas said he had about two weeks to build the T-shirt cannon, including the time needed to order and acquire the parts.
