This is art. Love it.
It seems like an ok system if you don’t have to interact with your keyboard. But if you want to do away with the need to interact with the keyboard, a much more aggressive tilt could be used, right? This only gets you a couple inches. Ideally the top of the screen is around the top of your head, right? Of course this is for on-the-go use, so we don’t expect ideal.
Overall, it is art; I really do think it looks nice, but it is pretty impractical.
