entwisi, it's alright for you.......you have the technical ability to choose and change your operating system.

A lot of people(like me) would not have a clue as where to start such a task.........and worry that once we have changed(that is, if we could do it) the OS might not be to our liking.

Remember most of us have grown up with Windows of one grade or another, and therefore know nothing else.

Of those you mention, I have only heard of Ubuntu and linux( and really this is only because posts by you, and AndrewB, have mentioned them in the past).
