The HTC HD2 has a large 4.3 inch capacitive touchscreen and brings the Sense UI to the Windows Mobile 6.5 platform. It is powered by a speedy 1GHz Snapdragon processor and the device is beautiful. I have seen it a couple of times in person and think it will be a popular device for HTC when it is released. It is shipping in Europe and will be available in mid-November for Taiwan with further Asia availability over the next month.
AT&T and T-Mobile both have the HTC Touch Pro2, but AT&T also has the AT&T Pure Windows Mobile 6.5 touchscreen device so do they really need another? AT&T also has the iPhone 3GS and this device has a look and feel similar to that device so AT&T may not want to have HTC and Apple compete directly for the same customer. AT&T is also good at ruining smartphones with all of their crapware while T-Mobile is very good about minimizing these intrusions so HTC would be able to release a better experience with T-Mobile. OK, did I justify it enough HTC? Let's please bring the HTC HD2 to T-Mobile.
