A spoof video for Gmail Blue features a straight-faced "Gmail Blue project manager" who says that "in trying to bring e-mail into the 21st century, we are faced with a challenge: how we do completely redesign and recreate something while keeping it exactly the same? The answer is Gmail Blue."
Touting the new e-mail program's reliance on blue fonts, blue colors, and blue buttons, the project manager says that "it's Gmail, only bluer." The Gmail team claim that inspiration for Blue came from nature but is "better than what nature created."
Given the testy relationship between Microsoft and Google, their April Fools' pranks could have easily been more vicious. But in keeping with the spirit of the day, I think the companies poked a few holes in each other without doing any permanent damage.
