The iPhone 4 was the first iPhone to sport a retina display. Beautifully animated at 60 frames per second. Then iOS 7 came out with transparency effects and the whole came crashing down to stutters, bugs and whatnot. It was clear you needed a new phone and your current one just became a lot worse for everyday tasks.

I predict the same is going to happen in the new version of iOS being announced today. Apple needs a reason to sell new phones but the current ones are plenty enough. So why not throw some computationally expensive bells and whistles to make everyone unhappy with their current hardware?
