I bought them a modern Android tablet ... and I'm still stuck holding an iPad that can't do much of anything.
I'd love to get it running, as you said it's still a very capable device and if nothing else would be a good digital newspaper for the bedside. Unfortunately, I think it's toast and I'm going to have to send it to the recycler.
Also it's more than a little weird to expect a V1 product in its genre, from 2010, to still be useful 7 years later. I think your expectations are all messed up here.
