I was working with my iPod for music while running the other day, and because of my experience with my Android phone, I was wondering where the hell the menu button was! I only wanted to press it to see what cool stuff I could do with whatever app I was using, but it was nowhere to be found and I was constrained to a few buttons on the screen. That annoyed the hell out of me and I wasn't even using it for more than music.
iOS and Android are built for different purposes. iOS is built for people who don't want to get to know their phone and want to do very simple tasks. That's why there are no buttons at the bottom, no notification pull-down bar, no three different ways to lock your phone, etc. Android is built for people who would like to do as much as possible with their phone. That's why you can overclock your phone, root it, customize it like crazy, have widgets, etc.
It really comes down to the type of person you are. It seems like a lot of married guys here say "well, my wife really wants to go with iPhone." The reason for that is that your wife probably doesn't want to deal with complicated software. That's the way my mom is, my girlfriend is, a few of my good friends are, etc. Essentially, dealing with a drawer of apps is their idea of functionality. When I was explaining Android to my friend, I found it pretty hard to explain. He had billions of questions on how to do certain things. He no doubt would have gone iPhone if given the choice.
P.S. People talk about choppiness with the Android UI and stuff. What phone are you using? Sure, I had choppiness with my Droid Eris, but my Dinc runs very smoothly and I have absolutely NO qualms with it. If I use it a lot, the battery runs dry. If I don't, it lasts a long time.
