Critically important question: Do these accept the current iOS updates? The one I have, which is generation 3 or 4, does not!
Google says iOS 10 is the latest for this generation.
I’ve had one of these iPad’s since the Black Friday of the year of their release. This thing has been a workhorse and always performed really well… until recently. The software of iOS and the apps themselves have finally started eclipsing it’s capabilities. App hang is becoming a frequent issue, and as stated above it is not compatible with iOS 11+.
It’s a solid device with a good screen but know what you are getting into. Don’t expect this to be anything more than a borderline obsolete tablet.
