I picked up an iPad 2 16GB for next to nil last week to see what this was all about. It's fast, it runs smoothly. The battery runtime is absolutely insane. I've found myself using it for reading a lot more than I thought I would have.
Simple answer, because old doesn't mean useless. It doesn't need to die with dignity because from a usefulness perspective, it isn't ready to die. But I figure as a project head of a team of developers enabling OS X to run on older machines, you're fairly familiar with this concept.
Agreed. I had my iPad 2 for a long time. While I enjoyed it for light use. It just didn't work out to well for productivity and development uses as I was going through software updates. It belongs to my Grandfather now while I got the Air 2. He uses it everyday.
Still I wish I knew how to modify iOS 9+ just like I do with OS X on some of my old Macs. I would've had that thing running better than when it was new.
