If you move between systems or simply want a cheap USB key that contains your favorite apps for use in internet cafes and the like then this list from my fave free and shareware site SnapFiles is where you need to start.
I’m impressed by the amount of sys-admin style apps that are included here. Very useful if you need to run a quick port scan on site
