When I run who on my ubuntu laptop I see myself listed twice. Once with pts/0 and once with pts/2. Why is that?

    These are different pseudo-terminal devices allocated to the different terminal emulators you have open. pts/0 actually lives in /dev/pts/0.

who shows each terminal you are logged in on. Separate terminal emulator windows (gnome-termal, xterm, etc.) and ssh instances are treated as completely separate "pseudo"-terminals, and therefore listed separately. When you ran who, you must have had two terminal windows open. If you try it with three, you will see yourself listed three times.
