1) it costs money (the world has moved on the free os's)
Agreed, it does cost money and I don't see that changing. The world has not moved on to free OS's since the majority of computers uses Windows, most people pay for upgrades. Macs have just a 10% marketshare, Linux even less (non enterprise). Even Linux in the enterprise is not free, i.e., Redhat.
I think you're opinion may be in the minority, those people who use win8 tend to really like it, and the prior version windows 7 was very well received. I've not had any issues running windows 8, other then driver problems and those issues were the result of Apple drivers, so if you're going to blame anyone for that, it would be apple.
Overall, win8 has been solid, stable, and fast. It runs all the apps that I need without any issues, and that's the job of an operating system.

As for the OP's comment, back when windows 7 hit the streets, the MS developers were unabashed about their attempt to copy OS X's eye candy/UI. I can't see much as changed since then.
