"With the introduction of the laptop, the mobile office was created. You could take your show on the road and get some serious work done. Of course, you still had some limitations. Even today you have limitations; unless you want to carry around a laptop that weighs 10-15 pounds you are stuck with a small screen size.
Fortunately, you do not have to buy a gigantic laptop or one with an extended screen that will cost you an arm and a leg. Mobile Monitor Technologies has something that can help to overcome this limitation; the Field Monitor Pro."
