I would want this. This is basically how I use my laptop. My computer I use both at home and at work and plugged into extra monitors, keyboard, mouse, headphones, internet, power, etc at both locations. On the road it is nice to have a screen and keyboard, so if my computer was my smartphone I would have to carry a little screen and key board (I already carry a mouse). I wonder if such an inexpensive screen exists not attached to a computer like an iPad or tablet.
