As a counterpoint. My first generation iPad released in 2010 can still be used to watch Netflix, Hulu, Plex, and a few other services.

Spotify works as does iBooks, Google Drive (reading PDFs), Mail, Calendar, etc.

I reset it last year and redownloaded old versions of all the third party apps mentioned above.

Now Safari on the other hand, crashes constantly.

I do have the newest non-Pro iPad and of course it performs better.
