One would argue that Linux has stalled OS evolution. It's free so there is no incentive for other innovators to come forward and invest massive resources and capital. The OS investment at all major companies had been drying up. Think about it, this is now almost 50 year old OS. There have been virtually not much of research, advancement or evolution even when *inux has several opportunities to rethink design and architecture in so many areas. To a common user, it's even hard to use, manage and understand but we are still stuck with it. We carry almost half a century worth of historical baggage with us every day with no end in sight. Here's interesting reading: http://doc.cat-v.org/bell_labs/utah2000/utah2000.html http://doc.cat-v.org/bell_labs/utah2000/utah2000.html You will see this pattern virtually everywhere when free software has become standard and it brings to halt research and development in that area that may require large scale capital.
