1) Alternate Keyboards
Android supports multiple keyboards and makes them easily installable; the SwiftKey and Skype apps all provide ways to quickly change up your keyboard style. Other mobile operating systems either don’t allow extra keyboards at all, or the process of installation is time-consuming and tedious.
2) Wireless App Downloads
Using the Android Market or third-party options like AppBrain, allow you download apps on your PC and then automatically sync them. There is no plugging required.
