Apologies for jumping in here, but hopefully parent will answer your question. I have noticed that a lot of the reviews & comments about the new Magic Keyboard for iPad Pro are separated by size. People who have the 12.9 seem to be much happier (on the whole) than people who have the 11. I have the 12.9 and I love it. The keyboard is fully as large as a laptop keyboard and the trackpad is smaller than a MacBook's, but still very usable. The 11 users complain that many of the keys are too small and the track pad is just too teeny to use reasonably. Obviously, physical input devices are very personal and have much to do with your hand size, your height, etc. I will say that one downside is that the case is heavy. It makes the 12.9 fully as beefy as the 13 inch MacBook Pro. The upside is that the ease of pulling the iPad away from the case encourages using the iPad naked (when a keyboard isn't needed), which is so nice for lap browsing, comic reading, etc.
