I think it may have been an understatement to say that HTC was working overtime last year. Not only did the company assist in the launch of Google's Nexus One and is rumored to be whipping up a tablet, but yesterday at the Microsoft CES press conference, CEO Steve Ballmer introduced the HTC HD2, which will be released exclusively on T-Mobile. The super thin HD2 comes with a high-res 4.3-inch touch display featuring pinch and zoom functionality (which is great for resizing web pages and notes), and runs on Windows Mobile via a 1GHz Snapdragon processor (the same processor stocked on the Nexus One).

The smartphone comes standard with GPS and a 5MP camera with a dual LED flash to add extra light when you need it. The HD2 is slated to be released sometime in the Spring on T-Mobile, and you can sign up to be alerted when it drops.
