@ Jacqui / Cost Benefit
Finally, a mature response from someone not afraid to put a name to their comments. I tend to ignore anything from an AC because they're either trolling or ashamed to put a name to their comments.
I work in the public sector. The machines I manage are about 4 years old, but do everything they need to on XP. I'm not going to waste taxpayers money replacing them with suites of shiny new PCs just so they can do *exactly the same thing at exactly the same speed* but on a different OS.
Yes, 7 may supposedly be more secure and manageable, but that doesn't justify the cost or environmental hassle of scrapping perfectly good machines and replacing them with something new that can run 7.
The OS is supposed to work for us, not the other way round.
