You do know that most of the "Android" phones sold in china are not Google Certified and do not use the Google apps. As a result most of the phones sold in china do not get reported to Google as activations.
The big difference if Yes while apple is an American Company they don't make much in America. Would you buy a Korean phone made by Koreans In Korea or an American phone made in china. Besides overall Quality wise I would say an S III is a Lexus while a iPhone is a Chrysler.
I notice a lot of people confuse the words invention and innovation. Some people on this site praise one companies innovations while ignoring another saying it is not important. It seems some people let there hatred/love for one company or another blind them to the truth open your eyes and look at the real innovation these companies are working on.
Besides RIM is the only ones innovating
The reason that Samsung markets it is because it is extremely simple. Simply tap to phones together to share something. They are not marketing this for the ability to share stuff by tapping stuff back to back samsung is marketing this to share the stuff easily. Can you simply tap any iphone together to share? (without an extra app?)
Yes the iPhone 5 is outselling the Galaxy S III but lets compare the numbers for a bit. lets compare the sells of the iPhone 4 to the Galaxy S (and it varients) then lets compare the sells of the iPhone 4s and the Galaxy S II. You will see the as both phones increase in the amount of units sold...The gap is getting smaller.
The android notifications you drag the notification shade down from the status bar. In truth the notifications in android are superior to Apple's solution by a longshot. The samsung solution not so much. I hated the notifications on Touchwiz on my Galaxy S III but my nexus 4 its a pleasure to use.
