Actually if they make an iPad with 3:2 aspect ratio it won't be cramped any more of all sizes from Mini 7.9" to 12.9" Pro.
4:3 Aspect ratio of an iPad is the reason why it feels cramped, it is less wider but soo much taller, 3:2 for at least the safe zone not too narrow and too tall. 4:3 nowadays is soo 90's like my grandmothers old black and white TV
The issue isn’t aspect ratio. IOS will not allow you to have two documents from the same app open side by side. So, for example, you can’t have two Word documents open at the same time. You could kind of get around this by having a Word and a Pages document open, but then you are going to run into some formatting issues. Same is true of spreadsheets and presentation software.
Anyway, why fight it? I really don’t see what a student gains by having an iPad only. If you wait for good sales, you can own both for about $1,000. Most students in the US are paying between $100K and $150K for their education. So, I don’t see the economy in spending at least $800 for a iPad Pro with accessories vs $1,000 for a MBA plus standard iPad. The $200 difference is spread over a 4 year degree that is costing you well over $100 grand. I wouldn’t want to hamper my acedmic effectivness and huge college investment because I lacked the right tools just to save couple of hundred bucks. We call it “stepping over dollars to pick up dimes”.
