Every year, I’m always curious to know how the latest version of iOS works on the oldest compatible iOS hardware, and I always forget.

Thankfully, Ars Technica published two detailed looks at performance changes with iOS 8 on the iPhone 4S and iPad 2. Particularly in Andrew Cunningham’s article, it’s clear how Apple’s march towards larger screen sizes has been driving software features that take advantage of pixels to offer more room for information, search results, or toolbars.

I’m not sure I would be able to enjoy iOS 8 this much on a device like the 4S. Hopefully Apple will improve performance on older hardware like they did with iOS 7.1.
