Pocketnow have published some video from the Windows Phone 7 launch in New York yesterday. The above video is for the T-Mobile HTC Hd7, showing an interesting feature, the stereo speakers with Dolby Mobile technology, which with the kick stand and massive screen confirms Microsoft does not intend the device to be used for spreadsheets.
Below is the HTC Surround, a similar media-centric device, where the speakers are even more prominent, and are sourced from Yahama. The HTC Surround should be available from AT&T for $199 on a two year contract from AT&T, which seems a but high considering the younger audience they seem to be targeting.
