What do you do when one laptop screen isn't enough? Right now I'm looking into options. I'm a big fan of Lenovo's portable monitors. Lenovo has an excellent build quality reputation and these devices seem intuitive and convenient. However, I am also wondering whether something like a pair of Xreal glasses would work effectively as an extra monitor for work related purposes. The fact that you would have one screen directly over your eyes and be looking through a semi-transparent screen to your other screen might be unworkable in practice though. What are your thoughts?
