iPhone has been around for quite some time now and I think people are becoming curious as to what has threatened Apple so much as to sue Samsung, the various law suites against Samsung have done nothing but boost their sales even further. But it's not just Samsung that recorded high sales since the battle begun, other manufacturers benefited as well, like Motorola, LG and Sony. What do all these manufacturers have in common? ... They are all using Google's smartphone OS called Android.
The point of Android is that you are not limited, you have the world at your fingertips, just waiting for your command and you can do it however you want to. If you find a few bugs in your app the real time communication directly with the developers, via the Play Store, helps to resolve these issues.
You also get regular updates for your phones OS, making your Android experience better every time. If your phone becomes outdated and the manufacturer is unable to support your phones OS anymore, there are developers out there that release custom software for these phones, such as xda-developers.
Android is going to be the dominant mobile OS, watch out for it.
