Since the iOS 9 update my iPad 2 is a miserable piece of trash: everything is sluggish beyond saving, and the rendering has been butchered on those low dpi devices (the old iOS designs looked crisper).
EDIT: Fix iOS version, whichever one ditched skeumorphism.
Not saying the contrary, just disagreeing with the "old iPads haven't been deprecated" opinion.
iOS 9 was released in 2015, so 4 years after the iPad 2 release.
I'd expect a $600 device to last a bit longer than that, and I'm sure the biggest IT firm in the world could easily create custom builds for their older devices: optimise font-rendering, properly convert assets to low-res versions, and disable (or degrade) the animations and transparency. If the internal OS architecture is sensible, these 3 adaptations shouldn't be that much work and shouldn't cause any bugs.
