not quite .... the operating system's kernel, that is, the brain
engine of the OS is open source .... but the graphical desktop
environment is not (well, yeah, there are free ones around ... )
.... but you'd have to pay for most ... that's where all the linux
vendors come in .... Red Hat, Mandrake etc ....
so it's not quite "free" .... though the open source fanatics would
have everyone believe otherwise .... hey, geeks got to make their
billions somehow eh ...
