Let me ask something... What would you be willing to do to escape slavery? Nothing and just accept it? Or try every alternative there is available if it sets you free?
And the percentage is now pushing 30% as Linux desktop, 80% as servers, and 100% of all appliance and robotic applications, Whole governments, and huge operations like the Hadron Collider. There is obviously a reason why they do NOT run MS.
Now let me share what I have found... Most times folks fight Linux is because hey fear change, or they do not have the skills to try something new.
One thing very cool about Linux users is free and gracious detailed tech support and they will stick with you until it is done and up and running as it should.
I have personally helped with around 20 installs by PM step by step here on the FR. Even sent out several USB sticks with a full OS ready to rock as an external OS, just plug and play...
I have 35 years in I.T. and made my living with Microsoft, Unix (HP, Solaris, AIX) Linux and Mainframe OS' over the years. In the past five years I've been somewhat of a Linux proponent/bigot.
In the org that I work in (a large multi-national bank) less than 5% of our desktops are Linux. 5% are Mac and the remaining 90% are Windows.
In the Server space, well over 60% are RedHat Enterprise Linux, 5% are Solaris/AIX and the remainder are Windows. Yes we have a Mainframe, I don't count that as a "server." It's a very large Batch Processing environment that stands on its own.
So I'm a little confused where you come up with that 30% Linux Desktop total. Is that the environment you personally work in, or is that some industry metric I've not seen yet? (A link would be helpful if it's an industry metric.)
