While I like that the keyboard is fully mechanical, the size to me seems like it will be a major issue. My mom has a Logitech keyboard for her iPad Air and that thing is just way too tiny for me and cuts a lot of corners to fit everything on it, lot of alt func for keys like Tab/A on the same one and so on. While the N9 keyboard actually looks to be a full keyboard the fact that the N9 is smaller than the iPad Air means the keyboard will be too. I don't have very big hands, but I don't even like keyboards on stuff like 13 inch laptops and can't stand using the keyboard on my dad's 11" chromebook.
