Is that they don't become obsolete as fast? My mother still uses a iPad 2. I sold my iPad 4th generation to my wife's cousin, and she and I now both have an iPad Air 2. And to be honest, I just sold mine because I could, not because I needed to upgrade to the Air 2. I think the iPad 4th gen I sold will be OK for at least 2 more years. And it wouldn't surprise me if it will get an iOS 9 update. Moreover, it wouldn't surprise me if it will get an iOS 10 update as well.
