The HTC Diamond was launched at the Soho Hotel in London. The device has some pretty nice interface tech that they're calling TouchFLO 3D that heavily emphasizes one-touch browsing and single-finger dialing. They emphasized web accessibility, zoom-in navigation with "just one hand" and not too many fingers.

The specs of the device are

· Windows Mobile 6.1
· VGA Screen Quad-band HSDPA 7.2
· One-touch navigation, including single-finger dialing
· An accelerometer that rotates pictures as you rotate the phone One-touch music playback with an animated music browser
· A heavily-animated weather forecast app Full-featured desktop-like web browser (Opera) with zoom-in tech that actually reformats to fit the screen upon zoom, although Microsoft promises IE 6 coming soon for it
· Youtube app and content playback Available in June in Europe via Orange and the "rest of the world" sometime later Orange music store, games, wallpapers, and ringtone downloads
· Orange mobile TV with up to 61 channels
· No normal headphone jack - gotta use HTC's proprietary USB dongle
· "Better battery life" than their other devices (although it uses a smaller battery than the Touch - we'll keep our eye on this) -- will offer a bigger battery at a later time for those who are experiencing battery life issues
· No pricing info just yet
