In a lot of ways I agree with what Techman has said. Yes, the computer industry as we have grown to know it is making a huge change. For the first time, the most prolific desktop operating system, Windows, will have touch as is primary input method with mouse and keyboard being a "compatible addition" option. That is because technology is making a big shift away from the normal desktop environment.
Look at the monumental number of smart phones in the market. Look at the number of tablets (though it is expected this year tablet growth is going to start diminishing for several reasons.) However, the path of technology is slowly but surely moving away from the "wintel" box desktop and to integrated technology.
This was incredibly evident this year at CES looking at the amount of power and technology that is integrated into the next generation of TV. Your TV will have more connectivity features and integrated software than many may have on their computers. Voice control and motion detection control (think XBox Kinect) with access to all of your web browsing needs, video streaming, and even quad core processors for handling multiple tasks all at once!
All in all, it cannot be denied that Windows 8 progressed in the path that it did, which is to help usher in this new form of technology. However, for several of us tech people it also is kind of the sign of the end of an era. As a computer business owner myself, and a system builder, it's going to be a tremendously different market for me soon. This is the point where we have to evaluate the products we offer and how we present technology options to customers from here on.
That being said, though, the business environment is still very much dominated by the desktop environment. The corporate segment is an area proven to be behind the others when it comes to utilizing some of the latest technology, which is where the frustration of Windows 8 enters. I mean, a great number of places that we work on that have to connect in some way to a state government system still requires Windows XP and Internet Explorer 7 or earlier! Just this week while setting up a CNC router at our office I was told that I would have to run the system on a Windows 98 computer! It's to a point where corporate business trying to upgrade will have to completely revolutionize how they use technology which many are not ready or capable of doing.
