New product announced today by Studio Neat:
Canopy is a case for your Apple Magic Keyboard that folds open to create a stand for your iPad or iPhone. Now you can use a full size, honest-to-god keyboard with your device.
Looks very much like the old Incase Origami Workstation I used with my old iPads.
You can pre-order a Canopy now for $40. I've been using Apple's Smart Keyboard with my 12.9" iPad Pro since it came out, and I like it. I like the keyboard and the all-in-one nature. I'm curious about the Canopy, however, so I'll be getting my order in soon.
