Too big, too small are subjective views… It really depends on how people use them…Update:
Speaking to a friend of mine that had the Galaxy Tab S7+, which is close in size to the 12.9 Pro. He said that it was bigger than his iPad, said it almost felt too big. So he went with a newer M1 11" Pro.
Making me thing, should I just save a little dough and get the 11" and be done. Decisions, decisions, lol.
And there is also weight. On a desk, with a keyboard, the weight is irrelevant. On the go, with the Brydge keyboard you mention, the 12.9 is much heavier than even a Macbook pro (over 1.6kg), Naked it‘s 680gr for the new M1 or even 630gr for an older one like the 2018
