New iOS 7 outpacing even iOS 6 in rapid adoption by users
As anticipated, new buyers of the iPhone 5s and 5c are finding themselves prompted to download an iOS firmware update, v7.0.1, Apple officially states that the patch deals with "bug fixes and improvements," but it's believed to be focused on a problem involving the 5s' Touch ID sensor and iTunes purchases. It's unknown what if any changes the code makes for the 5c.
A new study by mobile ad aggregator Chitika has shown that iOS 7 is rapidly outpacing even iOS 6 in terms of adoption by users. Just 48 hours after the free upgrade was first released, 32 percent of the iOS device user base has already implemented it -- even despite some early strain on download servers in the first hours of availability. By the same point during iOS 6's release, only 24.7 percent of users had installed it.
Apple enjoys a significant advantage over other mobile platforms in that nearly every still-active device can upgrade to the latest operating system, and consequently nearly the entire user base does so within the first week or two of availability. When iOS 6 was released, it hit 15 percent adoption within 24 hours, and the first major revision (iOS 6.1) got to 22 percent in the first 36 hours of availability, and hit 60 percent adoption shortly after the first week.
The rapid adoption is important for developers, since it means they can focus their apps on the latest OS version and its technologies and advantages without having to spend significant resources supported older versions or creating custom versions for several iterations of releases that large portions of the customer base are still using, as with the Android system.
