No.. I think your find the 'free bit' refers to the pure and simple fact that Linux / open source software costs $0. It is cost-less, free distribution and re-distribution. Nobody is calling RedHat a full version.. it is when you get it from other sources that don't charge you (eg,

Windows XP Pro - £84 
RedHat Workstation - £67.99

Not that much difference.. especially considering you can download the non-pro version of RedHat desktop from their site for free.. Smiley
