While the Nexus7 gen 2 was, and to some extent still is, a great tablet. I don't think i would recommend anyone to buy it today. It's stuck on Android 6.0 with known security vulnerabilities and the performance is starting to fall a bit behind the software "development".

True, but you can get a refurb unit for about $100 and put LineageOS on it. We've had five of them through this house (the kids use them) and I haven't seen anything they want to do that it can't.
