How can you compare iOS6 adoption with Jelly bean when JB has not been released to 99% of users and the only 'adopters' I are those who own the Nexus tablet. Using what seems to be your logic, there is a 100% JB adoption as every device which has had JB made available to it has it installed. I Talk about skewing stats to suit your purpose!
Because JB is part of the Android family that provides - "choice"!
Regardless of Bean or cream or sandwich, adoption rates are painfully slow. Apart from carrier restriction most droids are not really upgradable due to spec restrictions and droid user don't really care what updates brings to them.
And who are you to say that Android users don't really care what updates bring to them?
iOS 5 is at 55% according to the linked chart.
If he have 100k downloads weekly and there are millions that just got a new iPhone, wouldn't most/all Audiobooks users that just got the new iPhone need to download? This group obviously uses iOS 6, and because adoption pikes at launch and then slows down, the net effect is that adoption is significantly overestimated. Also, those that use a 3GS and never downloaded his app, most certainly won't do it now, so they won't show up as well. same for other previous iPhones.
Perhaps if his apps have been updated for iPhone 5 screen size this might be true but other than that there is no need to update apps when going from iOS 5.1 to iOS 6 (or any previous iOS version for that matter). As for 3GS, why wouldn't someone download his apps? There is nothing to stop them based on os version.
Sooo, iOS6 downloads more ads than previous versions... or am I reading the second graph wrong? That first graph isn't showing me anything - what's it measuring? It can't be iOS version, if it were the second paragraph wouldn't say iOS 5 held steady at 71.5%, the graph clearly says about 90%. Why did you mention jelly bean? You are such a fanboy, be objective.
The methodology is nonsense. Counting people who are downloading apps isn't going to give you a representative sample; it's going to be overwhelmingly biased towards early adopters. In any case, we know the statistics are bogus because they don't add up: 35.4% iOS6 + 71.5% iOS5 makes 106.9%. Drawing any conclusions from these numbers would be foolish.
