I know that the older 12.9 Pro was frequently seen as too large/heavy to use comfortably on flights - but some comments seem to indicate that that's no longer the case with the new model. For those of you that have tried it, what's your take? And have flight attendants allowed you to keep it out, on and in use (in airplane mode) at takeoff/landing? For context, I'm considering buying it as my main device for trips, and using it without a case, carrying it in a minimalistic padded sleeve with a small folding stand (like the Plinth) and a separate folding Bluetooth keyboard. In other words, traveling as light as possible. Many thanks to all in advance for your experience reports.
