John Gruber on the slow adoption of iOS 8:

But it’s very clear that I was wrong about what the primary factor is. The simple answer was staring me right in the face. It’s all about the over-the-air update requiring 5 GB of free storage space, and many people not having that much free space, and not knowing how or simply not wanting to deal with it.

My girlfriend owns a 16GB iPhone 5s and I don’t think she would have ever updated to iOS 8 if I hadn’t done it for her. It’s not because she doesn’t know how to manage her storage, it’s just too much of a hassle to make room for some software enhancements that probably wouldn’t be missed if she never used them.

Apple needs to find a way to shrink the size of major iOS upgrades even further or they need to stop selling iPhones with such puny storage capacities. If they don’t, then Apple’s days of bragging about iOS adoption rates will soon be over.
