Yes, it is indeed true for other systems as well, although some configuration problems might arise, at least on Linux.
It is also true that there are several small Linux distributions which easily fit into a flash drive, and then you can boot from the flash drive. I used to use SLAX, this is module based, ie. you can choose which packages to install into the flash drive, and it has an R package, although R version 2.2, so it is outdated. But i'm sure there are more options, eg. Damn Small Linux is popular, i believe it is desktop oriented, so might not contain R by default. I used to install my whole Linux system into a small (ie. notebook) USB harddisk, this is very comfortable, you just boot from the harddisk and wehereever you are you get the same system (assuming you can find a PC, but usually this is not a problem). It was a bit slower, but much more comfortable than bringing a notebook with me all the time. Until i accidentally kicked down the harddisk from the desk...
