This puts MS Smartphone interface to shame.

I have a Tmo Dash and it does have very similar functionality, but not the polish this phone appears to have.

How did they get enough performance out of the device to do such slick scrolling? Why hasn't MS figured it out after all these years working on PocketPC / Smartphone?

I wonder what the unsubsidized price will be. Not sure I would want to pay $600 for a 1.0 device and be locked in to a 2 yr contract with Cingular.
