Got my hands on the Logitech K811 a few days ago.
It's pretty nice. It's about the size of Apples bluetooth keyboard.
It has illumination which is something apples keyboard should have if you ask me.
The main reason I like this keyboard is it's ability to swap between 3 diffrent devices on the fly. Also build in buttons like homescreen for ios is a nice extra.
