I use the 11" mobile almost exclusively.Maybe a strange question, but: How often do you compose on the couch, supporting the iPad with only your hand? I've got a 12.9" on order, but I'm afraid it's going to be too big. Everyone talks about the 12.9" iPad being great on a desk, but I'm trying to get away from my desk.
Staffpad on the couch with headphones on while my partner watches a show I am not interested in, in the bed, sitting on a balcony chair in summer, in the kitchen.
I can also put it down on a table all serious.
I wouldn't want to use a 12.9 away from the table at all.
The 12.9 is annoying to hold in one hand. It is also annoying to deal with in bed.
It feels like a laptop that's missing a keyboard. If you get it with the magic keyboard it's actually just as heavy as a laptop. It just becomes a beast that I don't feel joy to use but I have to approach it from a very "time to work" like pov.
