3. Customized desktop
Congratulations iPhone 5 users! You now get an extra row of icons that you didn't have with the iPhone 4 and 4S. That means you can see your TweetDeck icon and tap on it without scrolling over. The Times Square billboard writes itself: "iPhone 5: Now with More Icons!"
However, if you use any Android phone, you get more than just a static set of application icons on your 5 to 7 home screens. You have a working desktop you can fill with interactive widgets that show everything from the weather to your latest social media updates. I particularly dig the circles widget that Motorola includes on its Android phones, which shows you battery life, time, text alerts and local weather.
