I think after the baby boomers have left the picture in business, windows will slowly die out. Developers today are using OSX and Linux. Don't quote me, but traditional schools are the only ones using windows. My college does, and I honestly think its a learning point for all developers to know Linux over windows because of usage around the world. Tech companies are dropping windows for the opposing systems because of speed, reliability, and the current trend in design. With this happening all development, or at least what I'm seeing in the web, is mainly done on OSX or Linux. Therefore it make sense that lightweight containers will eventually eat VMWares lunch.
