Think of a world without Android OS, don't you think the world would not more easier like it us today just because every thing at my side changed after I change to Android from Symbian_ java.
With Android I have everythink like well designed IU, definity user friendly, edit my photos taken with more like hand camera, well I wanna say I mve with my camera in my pocket.
Android market is the most commonly used than any other, you need to have Android software to unlock alot that its capable of doing.
Like Android watches, tvs, automotives, phones etc,
Just try it now,
