Microsoft released videos of their new flagship mobile OS dubbed Windows Phone 7. Wired.com has a nice little write up on it as well as some videos. It appears to be fully integrated into Xbox 360 Live's Service and Facebook. Other features include Windows Live Search and other messaging applications. Other basic enhancements include a new keyboard style and menu system. It apparently can sync with Microsofts own Zune software similar to the way the iPhone can sync with iTunes.
