Andriod - The HTC MyTouch and DH has the G2 and we will likely exchange in the near future. After that, I see myself moving on to a Windows 7 phone. On principle, I don't see myself getting an iPhone in the near future.
I heart my Nokia E71 that I'm passing onto my brother but Symbian phones just seem to belong to a bygone era. I much prefer the solid feel of buttons and resisted the touch screen technology for as long as I could. But, since there are such good alternatives to the iPhone available now that I had to relent.
What do I not like about iPhones? Love the phone, absolutely, simply do not subscribe to the closed, controlled and expensive business model that comes with it. Unlocked iPhones cost $600 and above which to me is way too much money for a shelf life of 1 year.
What I love about Android phones is that the Android OS is open source, Linux-based, easily configurable, highly customizable and FAST. I can pick up a fairly basic Android model and still be pretty happy with it (excluding some models like the Motorola Cliq, bleh).
Anyways, that was a little insight into my smartphone decision making process
