Would be nice if they recommended a capture card that can actually take advantage of iPad's native resolution. The one they recommend is 1080p. That's good for Xbox, not productivity.
I tried it and it works quite nicely, but even next to a 14inch laptop it looks really tiny. Good for having a notepad on the side while you are fullscreen into something I guess (or sharing one screen with an audience while being able to check your mail, or take some notes, on the side).
I'd be more interested in matching the aspect ratio, since ipads aren't 16:9.
