Sam Moreau talks about the redesign of the Windows logo on the Windows Blog:
We have evolved from a world of rudimentary low resolution graphics to today’s rich high-resolution systems. And what started as a simple “window” to compliment the product name became a flying or waving flag.
It’s true that the Windows logo has long looked like a waving flag, which makes absolutely no sense. And the new logo is better. But it brings up a bigger question: why is it still called “Windows” at all?
Yes, the desktop variety will still have windows. But the mobile/tablet variety is geared towards the “tile”-style of Metro. In fact, as Moreau points out, Metro heavily influenced the new logo design.
To recap: a tile-based UI influenced the new design of the Windows logo, which previous looks less like a window and more like a waving flag.
Okay. I’m just waiting for Microsoft Windows: Tile Edition XP 2013 Pro.
