I wonder why they didn't take the logical next step and make it separable.
I like that they made the tenkey separate and also split up the space bar. I don't know how the switches feel yet of course, but the chiclet keys don't seem to be the best idea for an ergonomic keyboard.
I don't like the nav part they designed, and that the mouse can not be used left-handed.
