File this one as an minor change representing something major.
It appears that Microsoft, who have recently been adopting a new unified design style (previously referred to as Metro), are going all in with the redesign. The latest change to take place, according to the Official Microsoft TechNet Blog, is a new logo.
Now, quite a few people around the Internet have been critical of Windows Phone 8, Windows 8, Xbox, and various other products & services taking up this new design language; as the design gets pushed into the spotlight, users have been divided on whether the change is a positive advancement or a regression in functionality. To some degree, it could be said that people simply do not want change, or believe other changes could be made to retain functionality and attractive looks. However, it looks like this sweeping refresh of the Microsoft brand identity is not slowing down any time soon.
Head on over to the main Microsoft website to see the refined logo in use, and be sure to sound off in the comments on how you feel about the changes.
