Cramped might not be the correct word but each window will be small. Doing word-processing in 1/4 of a 13 inch screen is not preferable. Definitely time for bigger iPads. Even surface studio 2+ type of devices.it doesn’t feel cramped on a 13” when using it, really. That said the world is full of 13” laptops which use similar windowing systems of course, and they don’t feel that cramped either. That said - I would love a bigger sized iPad in the lineup.
