Ill preface my comments with: Apple didnt invent the smartphone or the general UI within. But, you cant argue that Android holds a candle to iOS. I had a 3G, then 4, then went to an HTC Inspire for a while...hoping to love it. I had to charge it constantly, UI felt unpolished, was saddled with AT&T bloatware, used more data without perceivable benefit, and the HTC touchscreen was possessed.
Sure, I could install boob shaker+ and customize my home screen to the Nth degree...but I'm back with the 4S now and it's so much better. Granted, many of the 4S criticisms are true (battery life and Siri issues). Phones like the Galaxy Nexus look fantastic, but not being able to sync to my iTunes and diminished battery life (if the Nexus follows suit with the other large Android sets): complicating my life too much.
Plus, the App store is so much better. Stay well
