Today, Microsoft made available the Windows Phone 7 Series Emulator which allows those desperate to get their hands on the Phone OS, a preview into what the OS will be like. Long Zheng has been posting the features to his website in the form of summary videos that show off some of the available features.
The emulator is primarily designed for testing your WP7S series applications, as it is a part of the Developer kit, but is an interesting look into the OS as it's not currently available to play with. The download weighs in at 75MB, and requires Windows 7 or Windows Vista to run. It's available now over at the Microsoft Download Center.
Other interesting details have been coming out of the MIX10 conference today, with videos detailing the Microsoft Office experience, texting, and the music hub in action.
