Re: Cost is the smaller concern
"In enterprises an annual licence fee is paid for every machine regardless of whether they 'already come with a licence'. And then there is Office licences, CLIs and such"
Only if they have an enterprise agreement and are using software assurance. For windows, office and CALS would not come to 700 per desktop in and enterprise, especially not in the public sector (they get large discounts). The only reason I can think it costs this is because they are paying for Microsoft to support XP still. Making them paying for Software Assurance, if they are paying, stupid as they aren't using it.
