As as standalone figure, that is true... in the same way as a routing protocol
metric of 23452 has no meaning on it's own.
However, if ( taking everything into account )
OS 1 costs 1billion to implement in an organisation
OS 2 costs 2billion to implement in the same organisation
then clearly we can make a comparison and decide that OS 1
has a lower cost.
The issue with the MS TCO arguments, is that they are not comparing
like with like - and that never works no matter how much you want it to.
The costs incurred in implementing the OS,
plus the costs incurred by the organisation maintaining the OS
and the costs of extracting the data back into a generic format to
move to another system should all be included in the TCO
Clearly OSS wins if you green field any site.
However, MS are claiming that the third one is a clear sign that
TCO with MS is lower, and I'd actually see that argument as proving
that TCO with MS is higher.
