I work with, and have trained technicians for over 30 years. Most of the tech people that I work with that have tried windows 8 , dislike it, and would not put it on their own machines. It's buggy, does strange things, is hard to navigate around in, and is really designed for a touch screen. For a Tablet with a touch screen or a phone, it is OK. Not for a desktop where you want to run several apps at the same time, like you can easily do with Windows 7, and I do frequently. Microsoft fired the designer of Windows 8, 2 months after it was released, and is reportedly already working on a new version called Windows Blue.
I won't argue with you on this, Bob. The interface is awkward for use with a desktop unless we were to use a touch screen. That is why third-party developers have gone on to create a start menu for the desktop!

When I read Sinofsky resigned, I knew inside this wasn't "to pursue other interests" as they say in corporate speak. He got canned for the way the product was implemented. He didn't listen to what the customers wanted. He did what he wanted and only what he wanted. He used this same approach with Office 2007 and Windows 7. The Office version was the first with the big button bar which everyone hates, and Windows 7 was successful. Sadly, he opted for something new without any easy way, as in built-in, to change the interface in Windows 8.
Now from a technical side, there are a lot of good things inside Windows 8 that most people don't see. The file system, based on Windows 7, is much faster because it is more refined. The OS is more strict and secure, and sometimes more annoyingly so, which is why some of the almost-Windows 7 compliant applications have trouble. I found that installing and running older applications as Administrator solves this issue. This is same in fact for running in Vista (gulp and barf), and Windows 7. The overall through put and threading model is more refined with few processes, making the OS respond faster. I noticed this when I had it running. There are tons of other things that I have learned about it while using it. I won't bore the others with the details.
In part a lot of the issues with Windows 8 have to do with the new interface which people aren't used to yet, and sadly this was something that sells to the public. It's all about putting your best face forward, and if you don't do it right the first time, well it'll be difficult to do this in the future. Again, if there was that option for the old start menu which has been around for about 25 years, there wouldn't have been an issue. This design was called Motif, and laid the foundation of what we have today with the File Menu, start-button, and the file manager we are used to today.

The funny thing is my former manager let his 2 year-old daughter use his new Windows 8 RT tablet. This little baby knew how to navigate around that machine better than any of us could, instinctively and naturally. The other guys, my coworkers, and I watched in amazement as she jumped from program to program easily. She didn't do this randomly, which was one of the first things I thought of. She knew how to scroll the pages to find exactly what she was looking for. We have to keep in mind though, she also knows how to use an iPhone quite well too, and has never used an x-windows environment (shell). So perhaps the concensus at Microsoft was if a baby can do it, it must be easy and natural for everyone else.
Windows 8 will be like Vista and Windows 98, which seems to be the way MS and other developers do it. It'll take a service pack or two or three to bring the os up to an acceptable level. Hmm... This sounds like Trainz TRS2006 to TS2009 WBE, to TS2010 EE, and now finally TS12.
