iPad mini (6th generation) vs iPad mini: should you upgrade?

If you're buying new, get the iPad mini. The iPad mini (6th generation) is no longer sold by Apple.

Two years old. A new model with an OLED screen is rumored.

The iPad mini is 3 years newer, so it will get software updates for longer and holds its value better. If your iPad mini (6th generation) still works well, there's no rush, but don't buy one new.
