Does Google Instant really work? I don't see it.

i know that. what i'm saying is.. notice that instant wasn't used. even though it was clearly working. that's what i meant by activity in the background. google instant working. not used. I've seen this behavior quite visibly around my university labs as well.

If you have seen otherwise do hit back. I'm trying to find out if Instant really does change the game the way they hoped it would or whether it's a few years ahead of its time since most people still type out the full thing all the same.
