Not the best but a great start. I have dream of something like this for so long. If and when they will get such app working great for tablets, it will really help drive the ridiculous prices for monitors down. Can you imagine using your 10" 1200 x 800 or soon to be 720p display as your field monitor?
This is very interesting. Someday with something like usb3 and a laptop it could be a monitoring and capturing device. I am really hopping that Nikon and Canon use at least USB3 to send photo and even video in the next gen dslr coming out.
