Google just got done officially announcing Google Instant at it's press event.
What is Instant? It's something pretty darn impressive, I reckon. It's about speeding up the time it takes to find something on Google. They even reckon that it can save you between 2 - 5 seconds per search and considering the amount of search the average user does every day, that probably would add up to a considerable amount of time.
Basically you've got use to suggestions as you type, but Instant speeds things up another level by dynamically narrowing down results as you type in the actual results area. It's wicked. As of now I have access to Instant in Taiwan using Chrome, but at the time of writing it wasn't active in IE and Firefox.
