Hi, iOS 9 has been released and I am cautious about upgrading my iPad 4. It shipped with iOS 6, and iOS 8 is already a bit slower and laggier. What is your experience with the newest update for ipad 4? Would you recommend upgrading or is it already obsolete? My bigger Question: Do you think apple makes iOS updates slow on purpose? I find it a bit suspicious that exactly after two major updates (two years) the third update makes the device sluggish, and that is the last update it gets. This definitely happens with all recent iPhones: The iPhone 4 shipped with iOS 4 and started lagging extremely under iOS 7 The iPhone 4S shipped with iOS 5 and started lagging extremely under iOS 8 The iPhone 3G shipped with iOS 2 and started lagging under iOS 4 already, probably because it really had a bad processor. It can't be a coincidence that after exactly 3 major updates, the devixe starts acting sluggish! After iOS 5, the most big changes were UI, nothing really big changed that could affect performance, and why would the performance worsen so regularly?
