Thinking about an Android phone

Greetings

I am torn between getting an android phone or an iphone.  I currently have a QMD and I'm looking to upgrade.  I like the iphone mostly because you can buy the itunes card and I don't have to use my credit card to purchase games.

With Android phones how do you pay for the games you purchase?  I would also kind of like to save money and not have to buy a new car charger because I've purchased a new phone.  My phone currently uses the mini usb charger.  I'm assuming all the new Android phones use this.  I don't really care about the 4g stuff because I don't even have 3g yet but I need a phone that picks up good b/c I live in a rural area and I know the iphone picks up good.

I'm also sort of leaning toward the android because they seem to be less expensive than the iphone.  Thanks for anyone that answers my questions or comments.
