Here's one for the road warriors... I like to use a second monitor but I move around a lot and have my office in a backpack. For some time now I've used an Asus MB168b attached to my laptop. It's a usb monitor so it gets power and signal through the usb port. Not the greatest resolution (1920x1080) but it does the job. I'd like to find something a little better that would connect through the mini display port on my Surface Book (either directly or through an adaptor). I don't mind plugging into a wall socket but the real key for me is portability, I need to be able to slip it in a sleeve and add it into my "technology backpack". Any suggestions?
