Forbes is asking the question if solutions like Docker mark the end of virtualization. Without getting into the debate of how containers can be a compliment to virtualization, it got me to thinking about how out of touch the tech news media is with the enterprise. Then comes the Windows vs. Linux conversation you’ve already had.
