Where is the swipe-right iOS 9 Spotlight screen on my iPod Touch?
That screen is not supported on any iDevice powered by the A5 SoC (so it's not on the iPad 2, iPhone 4S, or iPod Touch (5th-Generation)). Apple's older product support is great, I'd like to see someone even using an Android phone from 2011, let alone see that phone running the latest version of Android. Given that, this is likely not an example of planned obsolescence, but a result of the fact that the newer hardware found in the 6th-Gen iPod Touch is much more powerful than that found in the 5th-Gen, not just graphics processing, but more RAM (1 GB vs 512 MB), a faster CPU, and better power efficiency.
