I've been using the iPad pro 12" with the pre-existing keyboard folio from Apple for 2 years now and its my favorite device. I can't wait for the trackpad to be integrated.
I personally think this Magic Keyboard is a much better design than a kickstand to the iPad, and I think it looks great. Its reminiscent of the old 2nd Gen tear-drop-with-aluminum-arm iMac from the mid 2000s.
Its a different device category and target build quality, but my Nintendo Switch has a kickstand. It never works the way I want it to. I think on-device kickstands are tacky and liable to break, not to mention limited in function.
