Go your Gmail account.  Look in the bottom right hand corner.  See that blue button that is asking you to learn more about their new look?  Click it and upgrade!

Google officially rolled out their new look and, personally, I like it.  The addition of the bold, red buttons is visually stimulating against the white background.  The new spacious layout seems to be easier to read due to the space between rows and buttons.

Check out the video and decide for yourself whether you're willing to jump on the Gmail new look bandwagon.
