@Edvard,
Now we're getting into the deep end!

To be honest with you, Linux for me is like playing 3D chess.
I can play some chess (Windows) but 3D just doesn't make it in my head.
So, i'm trying to get more and more familiar with it by installing it and breaking it so that i can fix it.
I happen to "work" for a non-profit association and the folks know little about computers (let alone Linux!).
They get viruses and bring their computers to the shop @ $100 bucks a shot etc.
Their laptops have hard drive crashes, computers need replacement.
Those are big bucks for non-profits!

There are a zillion computers available on eBay that could be transformed with Linux and behave even better than Windows7 or 8.
I need to prepare the proposition by being more knowledgeable with Linux but especially so that they don't get lost in Linux.
Also, i'm fed up with the fact that Microsoft keeps on pushing us to new versions (which are often regressions) with a price tag that... well, you know the story.
Conclusion?
Well, Linux for me is a hobby still in the sense of not really taking the plunge (like yourself).
Why? Well, i have this CanoScan Lide70 that Linux still can't handle.
What do i do if i propose Linux to others and their scanners or whatever other application can't be connected?
Tell them to buy another scanner to have a free Linux system?
You don't leave a good first impression in those conditions now do you?
