As a person who used to work in the computer field, who knows many who still do, Linux or Unix, is an interesting thing to mess with but, if you have to get things done, you have to go with the standard.
Professionals, not geeks who have nights, weekends and holiday with nothing else to do, have to get things done. It is most efficient to use something that works most of the time, with the least amount of downtime. It is pathetic that that for most office and network stuff, that means MS products. This is a bit like using an automobile that functions only 95% of the time. The downtimes for linux/unix are much worse however...unless of course you have some pinheads to mess with the os and applications, most of which were written by amateurs. For graphics, the platform of choice is Apple.
For those who have no life, outside of playing around with some obscure, half-a__ed os and applications, by all means, let them choose linux or some other flavor of unix.

Wow! I havn't seen such a misguided, illinformed rant since Howard Dean spouted off on foreign policy.
