Take the latest change to hit the search engine, which is its presentation of image search results. Here is the old look for Google image search results:

Here is the new look:

You also no longer have to click through pages of results as they are now all on one page, although page numbers are assigned to show page breaks.

Now here's Bing's image search. A little more white space in Bing, but essentially the same look and feel:

In addition, Google is copying Bing's use of a mouse-over expansion of each image to give some details about the image.

All in all, I just find it interesting that while Google is the far superior engine in market share AND results, it is playing catch-up with Bing in how it presents itself. It's not the end of the world, but it does seem like a hat-tip from Google to Microsoft, which is just not natural.

What's your take?
