It's very clear that you could go to near 15" without having to redesign iOS. Software-wise, everything basically just works already. A 15" slot in the lineup would match Mac portables, and caters to Apple's profit margins & ever-increasing price points. It makes too much sense

I think it would be crazy *not* to expand to a larger iPad size as we move towards a shared Marzipan world w/ tabbed windowing, USB-C & more and more pro-level apps. As a product, I think it ticks all the 'should we do this?' boxes and moves into 'when should we do this?' instead

You could go beyond 15" with iPad, but then you start to need bigger changes to iOS (like a floating keyboard), and current side-by-side sizes become a little ridiculous to have filling the screen height. 15" could be done with iOS as we know it today without things getting weird

After 15” ipad, you guys will be asking 21, 27” soon

yes, I want a desktop one too

15" isn't /that/ much beyond where last year's 12.9" was in body size — that device had a 14.89" diagonal. You could easily house a 14.5" screen with the modern chassis design in a device like that

Altered keyboard design on the new iPad?

Wait! Hacking screen size on simulator is possible? 🤯

Uh....*Slowly hides schematics for a 17” iPad Pro, under the stack of papers* *Twiddles thumbs whirl whistling*
