I am planning to get one just to be able to run all the music apps I’ve collected on my older iPad, it barely runs those. It is my hobby that I sometimes have time for. As I can see, more and more music apps are being made for new devices and require more processing power. Also photos and video editing is what I sometimes do, so want it to be as smooth as possible.
I was thinking about 11’ at first but then thought “why not go bigger?”. It could be especially fun to use with music making apps for live triggering or slider adjustment. Still thinking whether should I do that though.
As for the mini I would probably considered one for the old days when I worked as PR assistant and needed to take notes at the events, though the larger 9.7’ worked OK for this, or I would naturally reach to my iPhone. But I understand that everyone has their own needs so there is a Mini. Though it would have been more popular with more processing power (not even OLED needed)
