HTC HD2, WinMo 6.5 native device, running 7 or 8 Android builds from the sd card.
It is a beast, 1ghz snapdragon (1st generation) processor, more ram than I've ever needed, huge capacative touch screen, and the ability to switch operating systems all day long if I want to.
I still love WM 6.5, I hate to see the 'locked down' look and feel of WP7 becoming so popular.
If I wanted to wander in a walled garden, I'd buy an iPhone, Windows was sposed to be a man's mobile OS
My Android builds range from cupkake to ginger, cyanogen to aosp, I love the variety and ability to customize endlessly, keeps me from getting bored and buying another $400 phone.
