yeah... this os war is really getting tiring...
it's your choice which OS you use, and thats what it is all about - the choice (yeah - everybody knows that MS is doing everything to not let people to have any choice at all, but everybody knows also that recently they are not succeeding in it as much, so I think it's not a problem, and definitely it can't be an argument for neither against).
That I've choosen some OS means also that I'd rather have problems specific to this one than to other ones (and every one knows that every OS has it's own specific problems - for some people windows' problems are greater/more anoying than linux's problems, and for others it's vice versa).
Besides - making someone happy by force (in this case: forcing him/her to use OS that you think is the best (even if your'e right)) can only make him/her (at least) mad at you (because you try to take away his/her freedom of choose). So it won't help at all.
In my country we have a saying - "officiousness is worse than fascism".
And Lava - putting those MS links everywhere can also be perceived as "OS extremism".
It's just what I think about it.
