I will travelling to my nearest Apple Store in the UK this morning. I am torn between the 13” and 11” iPad Pro. If this helps, I will be 56 this year. I have no problems with the 11” for general use. I even have my iPad set to use “more space” which makes everything smaller. That said, my eyes are not typical for my age as I do not need glasses for anything apart from very small text in low light. However, if you do wear glasses, I would imagine the 11” would be perfect for your needs.
I have reservations about the 13” iPad, which is why I am travelling 50 miles to see it in person. At the moment, I am typing this in bed, with the 11” iPad held comfortably aloft in my left hand and typing with the right. I need to be able to do this with the 13” or it’s a bust. I have held the 12.9” iPads before but I always found them too heavy and cumbersome. I’m curious to see if the much thinner/lighter 13 iPad changes the equation.mI’m gonna check em out on Monday & make the decision then. May swing past John Lewis as they may have older air pro 11” if Prob get pencil pro with Smart Folio case thing or Logitech combo keyboard, looks sweet!
