Dunno man, I’m on a 17 and there are a ton of context menus that were clearly not tested properly on a screen this size (6.1” or something) - the “delete” option is nowhere to be seen for example, you have to scroll down to find it.
Guess they’ll want us to carry iPads in our pockets for these UIs to actually work :)
Regarding typing on the iPad - Apple has removed the landscape split keyboard on the iPad, making it even more awkward to use, but not on the iPad Mini.
Perhaps they wanted to sell more Smart Keyboards.
