No offence man but lets be a little honest about things...

1) linux is difficult... not in the sense that it's confusing (I use it in a dual boot setting at my house) but in a sense that people are familiar with windows... the point is why switch... take cars for example... I drive a standard, I love driving standard and would never ever consider going back to an automatic... people don't just start driving an standard because there is a learning curve associated with it... most people feel comfortable with windows and therefore will have a hard time changing...

2) currently most new computers come preinstalled with Windows... which means that the people are already paying for a copy of the OS, so why would they spend the time getting another OS if Windows is already included...

3) windows won't be forced to make MP3 players copyright protected... that will be something that is beyond their control... they can't monitor every open source project out there... there will always be options out there... who knows maybe we will just have to move to OGG instead... big deal... I like OGG a bit better...

4) Linux does not work and look like Windows... personally I think Linux looks better and right now Windows is trying to catch up... but it doesn't work like windows it works very differently... Linux works on an entirely different mindset... how do you explain to someone who's used windows all their life that to get to their CDROM they have to mount it first?? or in the case of supermount that it's no longer just in the d:\ location that you have to go find it in /mnt/????/... or packages... I personally don't think that packaging managers have come far enough... I haven't used Debian yet... but most of the other package mangers are a pain with dependancies etc... there are some solutions like Debian's APT-GET and Sorcerer Linux, and I think GENTO linux or something that looks like that... where it takes care of any dependancies...

5) Linux is powerful and secure only if you have someone who knows what they are doing at the helm... most of the time the average user couldn't set up a linux firewall or any other settings to save their life... and downloading security patches isn't something that is high on most peoples list... also one of the reasons why we don't see a lot of viri directed to Linux is because there isn't a large number of people using it... no one would target the smallest portion of the population with a virus... but if Linux becomes more prevalant in the future more bugs and vunerabilities will be exploited...

I will level with you I enjoy both Windows and Linux but as far as what the general populous is ready for I don't think Linux is there... albeit the closest thing I've seen yet is Lycoris Linux (the old Redmond Linux) they have a pretty user friendly system... I figure that Linux will eventually be pushed further into the fray but at the moment it doesn't have the marketing clout or the familiarity that windows has... it needs time...
