Just got an HD2 to replace my Orange San Francisco. Totally love it, so much faster great build quality and no annoying niggles yet.
Currently running a 2.2 desire sense Rom using nand. Tried WP7 but honestly don't think its worth the hassle getting it activated. Besides doesn't seem that legal.
Are there any particular roms I should try out? Think I tried that nexus one but the image quality was poor. Might have been the launcher it was using though.
Not sure what you mean by image quality fella? Care to elaborate dude and maybe we can help you further.
I have had 18 Roms on my HD2 (they are all still on my SD Card.!) and there's no question in my mind that Nexus one is the best by a long stretch.
Since flashing the latest one which fixed a Bluetooth battery drain issue, I haven't even bothered looking at any other ROMs.
Anyhow a lot of the mature roms are all pretty good, it just depends what you want your rom to do / look like...ie Sense, Cyanogen etc
