We were frankly blown away with how slick this phone is. Mind you, WM 6.5 still shows its not-so-fresh colors here and there, but the general experience of using the device is handled mainly through the Sense interface, and it blows the hinges off of any other Windows phone experience we've had. Ever. From the lag-free gestures which get you around the device, to image pinching and zooming with that aforementioned multitouch, the hesitation-free jumps in and out of applications, and typing on the sprawling, HTC-ified onscreen keyboard, using the HD2 is a joy. There's no getting around the fact that the phone is still very much anchored to Windows Mobile, but what HTC has done here is nothing short of a revelation. Why Robbie Bach didn't bring this up on stage today at Microsoft's open house event is anyone's guess -- though we have to imagine that when your OS is this heavily gutted (HTC has even completely removed stock apps like calendar and contacts and replaced them with its own versions, and the company had to hand-roll the capacitive / multitouch interfacing), it might not be the best example of what you've done. We'll be waiting with bated breath till we get more hands-on time with this phone, but until then, we can all enjoy some lengthy video of the device in action... so check it out after the break.
Update: Second video is up!
