@NIB @neon_nova a lot depends on where and when you work. 13 inch is the ideal size if you have to work at the backseat of a taxi or in a plane.Once home or at the office, you simply connect your 27 inch screen to the 13 inch machine. For me this has been the ideal set up for over two decennia. Lately, I’ve been working with the X-Real glasses. Works fabulous if you are in the backseat and you don’t want to disturb your driver with a bright screen.
