I find Windows 7 fine and I like the fact I can choose the hardware it runs on instead of having Steve Jobs choose it for me. The screenshots in that article seem a bit silly - you could assemble something similar for the Mac without trying too hard  simply by picking bits of software written by very different companies. One of the examples it cites is from none other than Apple.
The look of MS Office, the software I use most of all, is very consistent, and a lot better than Office 2011 on the Mac.
