Dont forget that the vast majority of users either doesnt know Linux, distrusts Linux, has heard rumors at any point in time about some feature or component not working as perfectly as under windows, is uninterested in computers beyond their daily usage function, or finds themselves in a social circle or job environment hostile to Linux.

What Linux needs to get widely adopted is settle for one central distro, iron out all bugs and compatibility issues and do a bunch of testing with windows users to determine what differences they are confused by. The goal must be to create total feature and compatibility parity with windows, and make the whole process so incredibly simple that even absolute morons with zero interest in computers can both use it instinctively and not miss anything their windows used to do. Then run a massive adoption campaign.

Now I know many aspects of this are directly opposed to the fos ethos, but if Linux ever wants to claim market share they need to spend big on it and pick up the users where they are; in a place of zero user ability and a lot of ignorance.
