You win some, you lose some. In this case, the European mobile market is the winner of HTC’s newest handset, the HD2 (previously known as Leo), while the US is s#^% out of luck…for the time being.

This beautiful device is sure to make many a jaw drop with its glorious 4.3″ 480×800 WVGA capacitive touch screen display (i.e. “the world’s first capacitive touch technology on a Windows phone”) and 11mm thick thin body. But the fun doesn’t stop here, kids.

The HD2 is HTC’s first WinMo (6.5, in this case) device to sport the company’s attractive Sense UI. For those of you who are unfamiliar (er, live under a rock), HTC Sense offers:

a holistic experience that focuses on making phones work in the most intuitive way. HTC Sense is based on three core principles – make it mine, stay close, and discover the unexpected.

Along with all the eye candy, the HD2 is packing some serious processing power with the inclusion of a 1GHz Snapdragon processor and 512MB ROM. Other notable features include a 5MP auto-focus camera with dual LED flash, microSD expansion slot, 1230 mAh rechargeable lithium-ion battery, 3.5mm stereo audio jack, Bluetooth 2.1, GPS, Wi-Fi, 3G, and a whole lot more.

Look for this stunning device to become available “later this month with selected operators across Europe, before rolling out to other regions in the coming months.”
