I agree completely that it was, and continues to be, a mistake to think that all devices - from a phone to a tablet to a desktop and and/or should operate similarly. Form factors each come with their own strengths and weaknesses, and a one-method-fits-all approach is, by necessity, fundamentally compromised. Like you say, great idea on paper, but in practice, it just doesn't work.
That being said, I took advantage of the $40 intro pricing when 8 was released, and I've come to very much like Windows 8. Even disabling all things Metro, there's some nice features over 7 - amazingly fast boot times, far better task manager, various small enhancements, the clean visual look and file history (although I still use the previous file recovery service for scheduled backups, and I'm none too happy that it's apparently been forcibly removed from 8.1). I don't consider myself a guinnea pig, nor Windows 8 necessarily a Frankenstein. But I'll admit my satisfaction is, to a large degree, predicated on the $40 intro price. I upgraded two systems, and consider it money well spent, but the current price of ~$120 prevents me from upgrading any others. I'd spend that much for a new license (for a new system), but there's just not enough value in 8 (over 7) to spend that much on an upgrade.
