Except the boost was artificially higher this year because of how pathetic an upgrade the 4S turned out to be.
The overall long term trend in every country (even in the US) is still towards Android. People are becoming disenchanted with iOS and grids filled with icons, regardless of how many chamfered cuts Apple puts on their phones.
Dude you're trying too hard. So what if the 4S was a pathetic upgrade? Want to spend time commenting on the Nexus S being a huge upgrade?
You know, iOS isn't just about grids and icons. That's one element. Only a true fanboy would make it a point to say that people are leaving in droves because of that. Let's spin it the other way. People are disenchanted with the Android lagfest. Even 4.2 didn't solve anything. It's not fully 60 fps smooth, and even the iPhone 4S still feels smoother than the Galaxy Nexus.
There are certain things that keep people on iOS and certain things that keep people on Android. Honestly, the grid of icons isn't my biggest concern. I like Android's customization, but I enjoy my apps and phone more on my iPhone and spend less time worrying about when the next nightly will come out to fix the HWComposer on my SGS2. Customization is a never ending thing. The more you keep allowing people to do it, the more they will look for ways to change things up. That's great and all, but if you're into it, it never ends. You'll spend 10 hours having the perfect layout this week only to change it up next week with a new homescreen and lockscreen. Sorry, but that's just like buying every phone that comes out and every incremental upgrade. It's not worth most people's time/effort.
Why do you make it such an issue? Does this increased marketshare hurt you so bad you need to make a jab at Apple every second you get?
