You're half right -- it does represent the worst of Microsoft, but not because of new-for-the-sake-of-new. It represents the worst of Microsoft because it's entirely designed around
what Microsoft needs rather than what the
user needs.
Windows 8 is the way it is because of two things Microsoft needs:
- Microsoft needs to be relevant in the world of tablets; and
- Microsoft needs the market for traditional PCs to not evaporate.
So they built a product that is focused entirely on reconciling these two needs -- a product that tries, awkwardly, to serve the needs of both kinds of devices. A product that tries to make Windows relevant to tablets while at the same time not making tablets so awesome that people stop buying traditional PCs for them.
The result leaves users cold, because it wasn't designed for them. It was designed to meet Microsoft's corporate strategy imperatives rather than to solve a problem actual users have.
It's the worst of Microsoft because of this classic BigCo thinking -- the thinking that the problems products need to solve are the ones that are worried about in the BigCo's executive suite, rather than those the customers are worrying about out there in the world. It's inward-looking product design, which rarely works.
