There are plenty of PC's on a stick around. They are incredibly cheap, you will also need to lug around a keyboard and mouse, and have to find a screen and hope that it has HDMI, or that the HDMI hasn't been crippled on the TV, as many hotels do. So in addition to you computer that "is the size of a deck of cards" you are going to be carrying peripherals. That is just silly. I am looking across the room at the pile of Ipad's that have not been used in years as they are impossible to get real work done on (basically everything I did on my Ipad I do on my phone now). I have played with Chromebooks and the like and they have never been robust enough. Just use a good thin ultrabook like the Zen mentioned above, or the HP Spectre's or anyone of another half dozen 7th or 8th Gen i7's and you will be carrying around a decent screen, a lot of power and you won't notice it. Regarding all the fears of theft and other craziness above, I spend my entire life traveling abroad and maybe know one person who has ever had a laptop stolen from a room, phones on the other hand go missing all the time.
