I bought one of these when I was on an extended working holiday to use with my 17" laptop. Works very well, obviously you can't get a lot of stuff on there because of the small resolution, but when combined with the 1920x1080 on my laptop it is a good combination. You could easily buy 2 and have one either side of your laptop. Very light so can carry with your laptop on board a plane easily. It is not going to replace a 4 x 24" desktop setup but is a great way to have a functional mobile trading workstation.
