HTC has a series of demo videos over at their YouTube Channel focusing on the Titan and Radar Windows Phones. HTC has teamed up with comedian Jim Gaffigan to add a light-hearted approach to showing off the various features of the new phones and the Windows Phone operating system.
The short videos cover a wide range of topics such as the Games Hub, Office Hub, linked Inbox, Bing Vision and yes, Pie pie charts. There's about sixteen in all and if you're curious about what Windows Phone has to offer, they're worth checking out.
You can find all of the HTC Windows Phone videos here at HTC's YouTube Channel.
Thanks goes out to Robb for the tip!
