iPad mini thoughts?

Hi folks, the iPad mini is on some decent sales right now and I'm seriously considering one. I switched my phone to android a few years back, I think my last iOS version was 15.2 on an iPHone 8, but I really want the best of both worlds and have a few ipad mini specific questions.
1. Is it wide enough for comfortable Braille screen input in tabletop mode? I love BSI but wouldn't really want to use something bigger than a phone a lot in screen away mode.
2. How practical is it to split your screen between multiple apps using voiceover? The mini seems like it might be too small for this but I'd love to be wrong.
3. Since I'm mostly a braille screen input and Braille display user, would I encounter the same navigation issues in edit fields that show up for keyboard users? I'm not planning to do spreadsheets or heavy word processing, more like drafting an article in markdown where aI'd want a stable cursor. Are there any good apps that fit the bill with a Braille Display?
