this is so personal that you'll get tons of different opinion that match ton of different use cases...
If you use your iPad "à la Steve Jobs" on a sofa then probably no, 12.9 is probably too big for that.
I never, ever, use it like that.
I have the first gen 12.9 and the 11 pro so all the incentives to use the 11 pro more, right? Much faster, much lighter (first gen pro was the largest and heaviest), much nicer bezels, 120hz, better pencil etc... Well the one I use most is still the 12.9....
I never hold the iPad while sitting, I only hold it while moving around the house doing other things, but when I am in a room it sits on a stand (every room has at least one stand), and most of the time it's in my home office on his stand just above an Apple keyboard, ready to be used either in landscape or portrait mode....
It's still light enough (I used it naked) and snappy enough, and the larger screen is a treat even compared to the 11 pro....
