Google just implemented its instant searching, which populated search results as you type. For now, I don’t see a change in results in the new Google Instant search. And to be honest I am so in the habit of slamming down the “enter” key when I’m done typing, I’m not sure how useful the instant results will be, they just seem distracting right now.

The only benefit is the auto-complete (though its not without downsides).
