Oh yeah, please explain to me how you're going to attach an external monitor on your cross-country flight? Or how you're going to carry your external monitor over to the coffee shop down the road? Or maybe you're somehow going to explain to me how you're going to ship your external monitor to you at the hotel you're staying at in another country? Get a clue, dude. If you're not a MOBILE PROFESSIONAL, then don't make comments about what you DO NOT KNOW.
