Hello,
  

Stop , no more! That is _exactly_ the windows mentality I am refering to.
That is the whole point.

This , " I know what you want and need so I will take over and run your
system and your life just to be nice and user-frendly" is what we REALY,
REALY dont need transfering to Linux.
    

I know that this is not exactly the point, but I think the 
Gnome/KDE/whatsoever mime type handling can cope with multiple applications 
per mime type.
