Mind Architecture Tech Opinions

Youtube has become very popular and was recently purchased for a lot of
money. There are other companies out there that have been doing similar
things in a similar way(Google video is one, and they bought youtube). Do
you think Youtubes popularity was more a catchy name for the technology? Or
Is the name not as important as the features and functionality?

Microsoft pretty much dominates the desktop computer space. Many people view this as bad. Do you think the computer industry would be at its current level if Microsoft hadn’t unified things with 1 common OS? Is getting everyone buying computers because of Windows or was it going to happen anyway? Is it still a good thing that most people are standardized on Windows or would the industry be better off with more share by Linux and Mac?
