Re: What is this for?
"I've come to the conclusion that the only people who find a switch to Linux difficult are Windows-using IT folks of any age."
In my experiences switching people to Linux, the less complex software someone uses, the easier a time they have it. If they spend their time in a browser and word processor, it's relatively easy. If they use more things, the difficulty increases, especially dependent on their willingness to accept change and your willingness to hand-hold them through software they're unfamiliar with. The difficulty I cite when changing organizations is the product of all of those user problems combined and the changes required to get all the institutional processes and tools switched over, which you can do but is going to be a lot harder than switching your basic user was.
To clarify, that doesn't mean that it's not worth doing, just that there will be difficulty and, if you don't plan for it, it can go wrong and be abandoned. If you have a reason to do it which you can explain to management and a plan for how to accomplish it without breaking much, it's likely going to work. Unfortunately, I know a few people who want to do it without those things and, in my experience, they end up disappointed after realizing how far from optional those are.
