Peter Hi, yes, still using it w/ 9. I wouldn't mind a new camera, but at the same time, this device is pretty great for me.. very stable, I have everything set up nicely. I could see myself continuing to use it another 2 years as-is. I'm glad I got a good case for it, because I've dropped it a few times.
The X isn't my device, but yes you could use it especially if you put the brightness at 50% (and I also tend to be around there or a little lower/higher on the A70 too). The thing is though, even tho it's still supported by Apple, it's also now 5 years old.. so the camera would be 5 years old too.. I don't know that it's worth the bother.
I also don't know why people here are so into Apple.. it's a walled garden that is locked down. On Android I can do whatever I want.. I can sideload apps, I have a file explorer, I can use video containers like MKV, I can use different web browser engines, I can change the icons, etc. etc.
