Don't you EVER get bored of the childish "who has the bigger thingy"? If you want to use Linux - good on you. But please would the Linux world please stop hounding non-Linux folk with your "Micro$oft" is crap etc etc. Its so 1990's. And the statement Linux free - please use it sparingly - I have a 2000 user network and 150 server implementation. We have custom apps a help desk team etc etc. The cost to the company alone to reprogram/redeploy and retrain staff alone would cripple it.
Free??...mmm....damn it - you've lowered me to your level!! ARRGGHHH!!!
