My HTC HD2 is just a great phone. Everything runs on it, and its still pretty "current" software wise. The hardware is slowly getting old still, need to think about what to buy next soon.
And it's always good to read things like this:
HTC HD2 gets unofficial Android 4.1 Jelly Bean port, becomes the Phone That Would Not Die - Engadget
on your way to work on the very device they write about. (Only with Android 4.0.3 at the time). And others buy more current devices and don't event get an update to it.
