True, especially since neither "Linux systems", nor "Windows PCs serving the same function" have been around for 5 years, so estimating what they will cost over 15 years is stretching your data points a liitle toooo much.
I stuck with netware 3.xx for 15+ years and still using for my companies base ERP, so 15 year can't really be ruled out.
Sudev, I think I was unclear in my formulation.
I am OK with a 15-year lifespan of computers (on and off, I used mainframes till 1994, and were they old!). I am just not convinced that you can look at a baby a couple of years old, and predict how much its total expenses will be in 15 years.
Remember, Linux is just a couple of years old. Any data point on Linux, for corporate deployment, which is older than that, is referring to a very different beast. There is little point comparing RH7 with FC2, right? For MS, we have a slightly longer set of time series, in that the crucial difference is Active Directory, so we can extrapolate (or try to) 3 years to 15. Not much better.
Do you plan IT expenses over a 15-year term? Heck, does your company have a 15-year plan? I think these studies are using too little data to extrapolate too far. The maths is valid, the data is not.
