Second opinion
I conclude from all posting the following
1 Many people have not test the resent Ubuntu 12.10 and or a nearest distro's, but they comment. Nor have they test Windows 8. Therefore before you post anything test both and come back
2 Lot of people always want to have it easy. Although many people today's have windows, they have always their IT or someone else to show them the most stupid things, like how to play their movie for example. I agree with you that you need to search a little bit to run Linux at first, but once you learn to manage it then it will be easy to run.
3 Lot of people does not like learn something new. When you have born you learn to speak and read, but when it comes to computer they never open their browser to search how to solve their IT problem. They use their computer for entertainment and pay the IT to do the research work. Or some are afraid to fail in process.
4 Linux do not have the fair chance. If there was a possibility to learn Linux at school like windows do then windows was never become so popular then like it is now. The same way people have learn use Windows the same way could happen to Linux if there was a possibility.
5 Microsoft contribute to person will never change to other system. Microsoft manage to make their OS the most User Friendly by minimizing the use of command, that is a plus. Therefore many people think that the way computer should be manage is by the way Microsoft design their OS. Therefore, some people get stuck when they need to process some command.
What ever the above your situation I suggest everybody again to be open mind to any Linux distro's.
