If you're keen on the as-you-type search results you get from Google Instant, you'll really like Instant integrated with Chrome's omnibox. Just launch your beta/dev/canary release, type

about:labs. The instant result displays as a layer on top of your current page, and hitting Escape, deleting your search or clicking the 'x' button in the top left corner of the browser window. Check the video demo above of Instant in action on Chrome. It's awesome.
Currently Instant only appears to be a Labs option on Windows beta, dev and canary releases, but you can expect to see it rolling out to all Chrome releases eventually.
