I love my Android phone.
For me it's just a matter of having something different. The iPhone is not interesting to me... everyone has one, I have an iPod Touch that looks exactly the same and does all the same stuff minus the phone calls (which, is one feature of a phone I really don't even use

). I wanted something a little different so I got an HTC Inspire, absolutely loved it... ended up losing it in the movie theater and now I have an LG Nitro. Which I love as well.
I also think that the Android Market has more apps than iTunes.
