Currently, Linux systems take the very high end machines (any machine more powerful than a fully tricked out MacPro {read supercomputers and mainframes}), and the very low end machines (phones, routers, palm-tops, PVRs). In both cases, someone is missing. Microsoft. I do not hate Microsoft. Many people would think that I did (being a Linux fan, and to a lesser extent an Apple fan), but I really don't. I just think that they have failed to adapt to a changing market place, and I feel that they are stifling the progress of IT. Apple, on the other hand, has been aiding. Apple didn't reinvent the phone. Apple showed the a Blackberry/Palm styled phone could be made for the average person. They made it, and they sold it rather well. The iPad has shown that tablets actually are in demand, and for once someone has proven that Windows is not a requirement for consumer computers. The reality is that most people think of a computer operating system as inseparable from the computer itself. So, where are we headed?
