Change is the problem?
Sorry Jack, but I believe you missed the mark here as badly as the new desktop developers. First, I am a baby boomer, and change really doesn't bother me. What bothers me is poorly designed half baked products. What the real problem is is that the developers have little direction and spend way too much time wanting to be like Apple or Microsoft and trying to change a desktop operating system user interface into a smart phone user interface. Which make little to no sense. I have tried both of these new desktop interfaces, Gnome 3 and Unity, and both are seriously flawed from a desktop user interface perspective. When you change a simple one or two click process to launch an application into a fiasco, it's not called CHANGE or PROGRESS, it's called poor user interface design.
I have been using Linux for several years now and support it in our Christian school in both thin-client LTSP and regular desktop deployments. However, I have become very frustrated with Linux on the desktop due to it's instability and lack of printer support. Now these latest desktops are bloated, unstable, and are not really user friendly. I find Windows 7 to be far more intuitive and just works. Most of my users don't like Ubuntu due to these issues, and probably the CHANGE issues and would prefer Windows XP, which I have installed on several desktops. If money and supporting the evil empire were no object, then I would switch all the users to Windows.
Microsoft made this same mistake several years ago when they introduced Vista, which was never really supported by businesses and if businesses don't buy into it, then it will have very limited success. Remember Microsoft ME and Bob? Linux is killing their desktop success and will soon be relegated to server use only in businesses.
