Looking at that keyboard does raise one concern in my mind. The studio suggests OLED displays, but unless I haven't been up with the state of the art, their lifetime leaves much to be desired. I estimate that with 8hr/day usage the thing will flake out in a matter of a few months.
I'm thinking LCD might be a better way to go. A bit bulkier, to be sure, but they have the lifespan, are proven robust, and since they're embedded in keys anyway, don't need to be fantastically thin.
