"One problem with such articles is that they often get
tied up in buzzwords as the other camp, the proprietary software
group, rallies to defend its own turf.
"Acronyms like TCO (total cost of operations) and ROI (return on
investment) are flung around. There is talk, also, of how much more
a systems administrator who can look after open source systems will
have to be paid in comparison to one who is adept at looking after
Windows systems.
"In the past, there have been quite a few studies to "prove"
that the TCO of using one or the other form of software is less,
but then the origin of such studies generally results in much of
their punch being diluted."
