Right, so check this out:
I spend FOUR HOURS updating FNV in town at the library.
Then I come home, ready to play, and Steam tells me I'm back at 0%
EXCUSE ME STEAM? YOU WANT ME TO UPDATE FOR ANOTHER FOUR HOURS?
My battery is dying here! This time I'm going to shut off wireless when I go offline, so Steam won't decide to randomly start updating every five minutes.

Random
Random Steam is random, but in a bad way.
