Via SlashGear:
Microsoft is exceedingly excited about revealing the new look ahead of Windows 8 and Windows Phone 8, two new bits of software that they hope will revolutionize the way they do business. A rebirth of the Microsoft way is in the works, and with what they say is the 10th most visited website in the world being Microsoft.com, they need to be bright as possible for the new wave. Per Microsoft, this logo represents a “new era in which we’re reimagining how our products can help people and businesses throughout the world realize their potential.”
You can check out the logo at SlashGear. It certainly is an improvement, but Microsoft needs better products to go along with it.
