MacBook Air 13", power adapter, Personal Router (NEC Aterm WM3600R, for WiMAX), short USB cable to charge my personal router, iPhone 5, Sony CP-EL Li-Ion battery to charge my iPhone when necessary, short USB cable (with iPhone connector), OTP password generator, notebook, and pen. Sometimes, I use a Wi-Fi spot (Starbucks is especially good for that), and don't need my personal router, but I always have the latter, just-in-case. Power becomes an issue after a few hours because my MacBook Air is old. It isn't as easy as you might think working on-the-road. Will you be leaving your laptop out in the open when you need to go to the bathroom? Noise can be a distraction when working in, say, a Starbucks that is near a residential neighborhood, as opposed to one that is near a corporate setting. Telephone / WebEx meetings are impossible in public settings.

Environment for working is something I research before traveling (making sure there's ethernet in the hotel room or finding a spot beforehand where I can take scheduled calls).

I guess I'm really more concerned about the screen setup. Are there any foldable or portable monitors (~13") that work well when traveling?

Anyone ever tried using an Android tablet as a second screen for desktop?

Added: The personal router is a good idea, but usually just tether my Android to my MacBook if I need to supply my own data.

Whenever I need a second screen, I use an iPad connected to my laptop using Avatron's Air Display software. It works well for my needs.

I was hoping not to invest in an iPad (considering the price and way over qualified) just to use as a second monitor on-the-go. I'll look into an Android tablet while using a similar application since you've had luck working off a tablet as a 2nd screen.

Being able to hang a tablet off of your laptop's screen (like the way that kickstarter project mentioned by someone else does) would be nice. By the way, my laptop bag has a convenient pouch for a tablet.
