A lot of people have not taken this face lift positively and would like to still access the old Interface of Google. Yes, you can still do it without any hacks or scripts. It very simple. Instead of typing google.com just make

http://www.google.com/webhp?hl=all

your new home page and through this URL you can use the same old Google which you are used to.

For any change there are a good lot of people who would still like to use the old things. They need time to accept the change.

Even this link might not be available for a very long time but yes it will definitely give Google users a chance to get used to the new search interface.

There are a couple of options through which you can either narrow or widen the search results displayed. This interface looks a lot similar to Bing which has the search results displayed at the center and on the left panel there is a menu to help the user narrow his search.

We are open to change but at this point the menu looks a bit redundant. Probably Google is experimenting with this new design and once it will get a fair idea of how users are using these options, it will remove the redundant menu items.

Users are used to find these options on the top menu and with the left panel may be Google is trying to make life a little easier. It is definitely going to take some time before we get used to the new Google user interface.

Update: Access the Old Google Interface
