Hi 
It's good to disagree. I think that is how we develop new ideas or new things. Also if wee were all the same and all thought the same it would be mind-blowingly irritating (see various films such as "Logans Run").
If you try to do exactly the same thing in exactly the same way on a different system then it is not likely to work. Step forwards in a virtual world by moving the mouse or press the up arrow. If you are afk you would need to use your legs or arms (or someone else's) (ignoring those fancy motorised wheelchairs). Then if you try swimming - again, the up arrow is probably not going to help unless you are Lara Croft.
LibreOffice is NOT just a cheap knock-off of MS Office. It has different ways of doing things. A different ethos. Sometimes it does things that MSO can't. Sometimes it leaves certain things, such as emailing, to other products so that you can choose between alternatives to suit your needs. I tend to find it is the newer users that have not yet learned bad habits that find it the easiest to use LibreOffice. It's the people that have invested a lot of time into learning MSO and thinking the MS way that have more trouble with it.
My point was that people who have systems that do work well and smoothly often seem to be more willing to try something else. They tend to be the ones that have the most confidence.
Contrary to popular belief it's fairly rare for MS to actually develop something. They assimilate it. The creative work is done by small companies vying for recognition. When they make it big MS buys them out and absorbs the work, kills the competition, and is thus able to generate far more profit from the smaller company than the smaller company could have hoped to achieve. Usually it's a kind of win-win.
Errr, i am about to get thrown off this list again for disagreeing with the TDF viewpoint aren't i?
