Dont want to start a flame war, but I just want to voice my opinion...
No, it's NOT just due to the iPad users. As a convert from Android to iOS I can see why this is the case. Lets face it. iOS simply has more useful apps, more games, and more apps in general as opposed to Android and Windows Phone OS.
I know people will argue saying that they have all the apps they need on their android phone, but see, THIS IS NOT THE POINT. The point is, iOS has MORE apps, and games than Android, and FOR ME, PERSONALLY, that is very important.
Call me a fanboy or whatever, but I see the fact that Android doesnt have Infinity Blade as a huge problem. Why in the hell should I settle for less, when I can have more?
Yeah, yeah, Android may have more customization, etc etc... Who cares? It all gets old after a short while. Cyanogen Mod? Yeah.. Whatever. I have a Jailbroken 4S.
Small screen on my iPhone? Ok.. but it still has a much higher contrast than a Galaxy II S.
Best things is, the iPhone NEVER, EVER has any issues or problems whatsoever! It will never freeze, reboot, slow down, (even for a sec). It is visible in sunlight...
Virtually all games perform, and look better on an iPhone. And again, there is by far more of them on iOS, with even more coming! Android devices... with their Tegra 2 and 3.. and Ice Cream Sandwich... BUT WHERE THE HELL IS THE SOFTWARE TO TAKE ADVANTAGE OF ALL THIS?! Where are the new amazing PC like games... Apps, etc? I am still waiting to see an Infinity Blade like game on Android. Oh wait.. I am sorry.. There are none!
And what about fighting games? Street Fighter IV Volt? King of Fighters? Marvel vs Capcom? Might not be important for you, but important for me!
And dont even get me started about the camera. It's miles better than anything on Android. And with it's apps, yet even better. The iPhone camera has become a complete replacement for my camera. I sold my SLR and I never use my point and shoot. sure it's lacking in features, but most of the time, I was taking very simple pictures anyway... I care a lot more about taking that great shot quickly, easily and efficiently than messing around with bells and whistles and miss the opportunity. I saw pictures from Galaxy II S and the iPhones pictures are much, much better.
SD card? dont miss it at all. Most of the time I will never find myself going above 16 GB anyway.
When people say that iPhone is more popular because of the braindead masses of Apple zombie drones buying their products simply for looks and popularity, they are just saying that to make themselves feel better. The fact is, people buy the iPhone and the iPad because these products are vastly superior (usefullness wise) compared to Android and Windows offerings.
If that ever changes, I'll be glad to buy an Android device again.
