Google has introduced this nice feature of 'Instant Search'. So apart from the search keywords suggestions, they now perform 'Instant Search' as you key in! If you are not able to see this feature in your country specific Google Search site. e.g. google.co.in then on the bottom of the search page click on 'Go to Google.com' and enjoy this feature.
They have also taken care for inappropriate content. So if you type in 'porn' they do not perform this auto search. Nice, eh! You can turn off this feature from the down arrow to the right of the search box.
Here is a food for thought. How does it help to see results while keying in? To me it is fancy but of less use. But as always I appreciate Google for their work towards making search faster, easier and fun.
Another feature that I have noticed is the 'Something Different' section on the left panel (if you have not hidden the left panel). It provides similar suggestions. e.g. if you search for 'american airlines' you will get
delta air lines
