I’ve been running Android on my HTC HD2 for a while now and whilst it works well, the battery doesn’t last as long as with Windows Mobile 6.5 (although i’m not 100% sure why).
I much prefer Android as an OS compared to Windows Mobile and would have gone for a Hero instead of the HD2 but I was lulled by the fantastic hardware.
I also had a good idea that the fantastic devs at XDA Developers would be cooking up new ROMS as fast as Apples share price is growing.
Recently Cotulla of XDA has also ported Windows Phone 7 to the HD2 and whilst it’s not my first choice of OS’s it will be fun to try it out and see just how far off Microsoft is this time around. You never know they may have pulled something special off.
