I think it is more of a personal choice. The Droid is awesome & so is the iphone. I chose the iPhone before Droid was really advanced. Iphone is very easy to operate & has lots of apps. Verizon offers a program to connect your iPhone4 to use for Internet on your computer as well. I think it costs $20 a month too.
iPhones have more apps available, android phones have more features available to the apps. iPhones have simplicity, android phones have more customization. It really depends on what you want in a phone
