Windows Phone–a 8.5 minute video
Although I have several great ideas for phone apps, I don’t currently have the time to be exploring them. Many of my coworkers are much more deeply involved in the Silverlight for Windows Phone efforts.
Recently a beta of the tools was released, and Long Zheng of IStartedSomething.com posted a nice video walkthrough of many of the UI pieces of Windows Phone 7, as seen in the emulator that ships with the tools.
The video is 8.5 minutes long, but appears to be a good peek into the software experience: http://www.istartedsomething.com/20100713/windows-phone-7-sdk-beta-emulator-walkthrough/
