More and more SEOs are reporting seeing changes in Google's look and feel, which is obviously in its test phase for now.
Personally, I like it. It looks cleaner to me, and I don't mind the navigation on the left. Another thing to note, with the increase in real estate on the left, as opposed to the current placement above the search box, Google will be able to integrate more vertical search options, such as jobs, much easier.
