It's me again, see above.
I might add that migration could be a lot more expensive than staying with Windows, in fact it was like that in my department.
Windows: TCO 98 EUR/month, Linux: TCO 152 EUR/month. Why?
- General policy of our company demands MS Office as ONLY office application
- 2 proprietary special purpose programs we use are only available for Windows (but would not work under wine or crossover) therefore we would need to keep our Windows terminal servers (which is a high cost if you have to pay for it ADDITIONALLY).
- EDS does not support Linux in Austria, we could have payed them for Linux-admins on an hourly basis, and we would have to pay for Redhat support additionally. I know this is stupid, but outsourcing the infrastructure your company relies on is stupid anyway, it keeps you from making good decisions, because every experiment you would want to make would cost you double because EDS wants to get paid REAL GOOD for this. In effect OUR IT - policy is dictated by EDS, and there is no easy way out.
Do not generalize this very special TCO study, in effect I think if you have the guts to make a switch towards open source software as far as possible, and are not dependent on a buerocratic EDS team as we are, the TCO for Linux would show some 70 - 80 EUR/Month.
