I have an HTC Desire HD and I LOVE LOVE LOVE my phone. Especially now that they finally released Instagram for Android.
Only problem with my phone is that the touch screen has recently started playing up, but it is still under warranty, so I just have to send it away. I think it's a problem that you could get with any touch screen phone.
I will definitely buy another HTC when I decide to upgrade phones - but this phone is pretty awesome, I imagine it will be a few years before I need to.
It was easy to link my email addresses and FB accounts, I can buy music on itunes and put it on my phone with no problems, plus the model I have has a bigger screen than an iPhone. Cost me about $550 I think, although they're retailing for just under $400 now that the Velocity and One have come out.
Personally there's no way I'd switch to iPhone, even if App developers seem to forget Android users a lot of the time.
eta: go into a phone store if you can and have a play with the demo models, see what you like the feel of better.
I will admit I was also tossing up a Samsung Galaxy II when I bought my phone. I can't remember what made me go the HTC. Maybe cost?
