I hope I find it that simple in practice, I have my doubts with cramped areas like aircraft seats. I usually have the big window seat in the very front of the aircraft but with all the adjusted schedules find myself sitting in back to position for other flights frequently and I typically use my iPad Pro in portrait for reading back there. That said its too nice looking to pass up so we shall see how it goes...
I think the thing you’ll like best about the new Magic Keyboard, is the integrated trackpad, especially if you’re not currently using one. That’s been the thing that made my iPP 12.9 my daily driver. It was near impossible, especially on a plane, to work on spreadsheets using your fingers to try to select cells - at least for me it was. Now it works just like a traditional laptop, while still being so easy to transition to a tablet and touch interface. Having better key travel and backlighting will be nice too.
Report back once you get yours - I’m curious to know how it performs, before pulling the pin and getting one, which I’ll likely do regardless (unless it’s total crap). And as you said, it does look really nice, which is another benefit.
