Apple's own stats show iOS 8 upgrades have slowed to a crawl
Despite the introduction of custom keyboards, Notification Center widgets and lots more, Apple users aren't taking to iOS 8. According to stats displayed on the company's developer portal, the proportion of iPhone and iPad owners currently running the latest version on their devices stands at 47 percent, only an increase of 1 percentage point from two weeks ago. By this point last year, iOS 7 uptake was already hovering around 60 percent, according to analytics firm Fiksu. We can only speculate, but it seems likely a combination of very large install files, the bungled point updates, and the dropping of iPhone 4 support could be reason enough for many users to stick with what they know, for now. Or maybe they're just paranoid.
