My new keyboard just arrived about 20 minutes ago. Using it on my 11” gen 1 iPad Pro. I’ve been playing with it and I’m typing this reply on it. I also have the original keyboard folio so I can make some comparisons.
Keyboard action on the new Magic Keyboard is fantastic. Key press is shallower than a Mac Magic Keyboard (have not used the new 16” MBP so I can’t compare), but feels way better than the butterfly keyboards of the previous generation Apple laptops. Excellent tactile action without being ”clicky” or loud. And miles better than the rubber dome keyboard of the older iPad keyboard folio.
Backlighting is excellent and adjustable from the iPad (Settings -> General -> Hardware Keyboad).
Trackpad is nice. Smaller than on a MBA or 13” MBP but just the right size for an iPad, IMHO. Clicks anywhere — not a diving board-style mechanism, so one can click at the top edge and it still responds. But also not electromechanical/taptic, which is fine by me. Microsoft Word doesn’t yet seem to be optimized for the trackpad cursor control, but Pages, Safari, Mail and others seem to be. Citrix doesn’t seem to be updated for it — the trackpad tap functions like a screen finger tap, but the remote pointer doesn’t really follow the trackpad cursor “arrow” (dot). Don’t know about Microsoft Remote Desktop but I suspect same deal there too for now. Haven’t tested any other apps yet. Double clicking on a word to select works as expected, as does right (two finger) click to reformat selected text, two finger scroll, etc. If you’re used to a Mac trackpad, the iPad’s will be second nature with zero learning curve. If you’re used to a Windows trackpad, it might take a few minutes to adjust.
Weight. OK... it’s heavy. I have the 11”, so it doesn’t weigh as much as the 12.9” model, but it’s definitely around 2x the weight of the keyboard folio. But the weight helps stabilize the cantilevered iPad, so I guess it was necessary. Most of the weight is in the keyboard itself and not the flap that attaches to the iPad. But yeah, you can feel it. I think weights were posted somewhere, but almost as heavy as the iPad itself. Together still a bit lighter than a traditional laptop, but definitely heavier than the iPad Pro by itself in a Smart Cover/folio.
Viewing angles are nicely adjustable. Would have liked it if the secondary hinge tipped back just a little more, but it’s not a dealbreaker.
Around the house I probably won’t keep the Magic Keyboard on unless I’m doing some work on it (emails, etc), but when going out and about for work (whenever quarantine permits), it’ll be coming with me.
