"While I don't think he is really against Linux
adoption, I do think he went trough a little to much effort to make
his statement. I think according to his conclusions I'll have to
clarify some points in response.
"Lower TCO
"1. "Here the author makes and disproves his own argument; Linux
does not deliver a lower TCO than Microsoft Windows server if the
administrative costs are admittedly higher."
"This is not what I stated, the overall cost of administration
is lower, because less people do more work. This more than fully
compensates for the increased cost per administrator. Doesn't it
give an indication if something is more expensive by the way? It
has more value, because it is more efficient. So in my opinion this
argument still stands."
