I've been using a pico or mini PC (mostly) myself (when I don't want to carry or use my laptop). Full blown Windows box that I can also store media on. My only beef is carrying a wireless keyboard/mouse (microsized) that are lousy. When flying, I use my portable monitor (that won't get crushed by the airplane seat in front of me) and gives me additional space to mess around with. Looking for a better KB/MS combo I can use that won't destroy my hands.
