key mapping convention

[Christopher Küttner]

Hi All,

please apologize if this off-topic.  Well, I don't think it is ot, since 
this problem is generated by Emacs.

I am using the mighty Editor since a few months now and I must make a 
decision.  Should I tweak the Editor to work like my operating system, 
that means using CUA and so on.  Or should I tweak the operating system 
such that it works like the Editor (eg C-y as "paste" ect)?

I want to decide this once for a lifetime.  Which is the way to go? 
Which way is better? Where is the origin of the way Emacs does it? Any 
thoughts, scientific or religious are welcome.

Thanks,
Christopher
