I'm still new to a phone with an Android based OS (currently owned a Galaxy 5 phone), and i say that the way you have control in your OS is better in this OS rather than in iOS (haven't tried in Windows mobile). I've used to have phones with symbian os (nokia phone mostly) but with experience with android, you have a full freedom to do what you want (well not almost) from the homescreen, to its programs, to customizing every aspect in the OS

and yeah Android still growing now a days, and still beating iOS
