Familiarity is definitely a selling point for many going to an iPhone IMO. Many people like the comfort of not having to learn a system that's entirely different; completely understandable. I don't really see how fragmentation is a problem (assuming you mean diversity of devices, system versions, etc.). It gives more options and allows the user to choose what they wish exactly. If you want a cost efficient phone with a good camera, you can have that. If you want a pocket computer, you can have that. Options, to me, aren't bad.
To me, "fragmentation" is a keyword that gets tossed around a lot, but never receives much in depth consideration.
If customizing didn't matter, would there be jailbreaking and theming??
Next point... Can I take your narrow minded comments of "We don't care!", in which you are speaking for the ENTIRE community, and categorize all iOS loyal users as **********? No. That would be silly of me, yet you speak for everyone.
The OP is asking for advice on Android vs. iOS, that's what people here are doing... When they aren't personally attacking each other *ahem!*
^^^^^
Holy crap! A rational Android lover?! That simply can't be!
Jailbreaking and theming, in the grand scheme of things offers more functionality in what again?? Apps don't matter? You've obviously bumped your head if you think content in the App store is irrelevant. Get that noggin looked at by a certified professional and offer something of substance next time you troll the Apple boards. Oh, Android boards don't do it for you anymore?? Find a lake and cool off. You're Welcome.
