@bpratt, notice you have a HD2. I'm luving running Android on mine as a WinMo dual boot using the Miui sd card ROM.
I was going to give that a shot, but decided it was time for a new phone, so grabbed a Galaxy S II. Much nicer phone and battery on mine with the different rom gives me nearly two days.
Still have the HD2 here, so might have a bit of a play with it, and keep it as a back up phone.
Shame the world revolves around the iphone with all the 'me toos' , as Android works great..... they reckon the S II is a iphone4 s killer.
