When Microsoft was released ages ago, their logo was the same colors (Blue, Red, Green, and Yellow). Over 20 years later their logo has not changed much, but with this slide that will not be happening comes a little change. The logo has simple lost the inside, and is just a line. The Windows Phone logo is a bit more simpler with just a green line looks like the desktop logo.
This is not happen, but it seems very cool, and would have loved to have it replace the boring old logo we already have.
