I used to have this tablet and it indeed was revolutionary.
Actually in my opinion Apple became a role model in tablet production, because competitors started to produce very look alike models.
It’s not bad, it’s a typical situation when you can’t create something better you just replicate.
This iPad has been serving to me for several years, maybe even 4 or 5 years and after that I sold it because I didn’t want to play games anymore. I used ti for games primarily.
