Have you forgotten that virtually anything Ms bundgles in, so does Apple? Why do you keep saying I buy into the Ms marketing? Boggles the mind. I mean name one program on windows that mac does not have an equivalent for. I think apple bungles even more apps in but I have not bothered to count.
One could say that the most basic text editor is a bungled app.
Did ya miss that? You seem to be trying to cherry pick here.
And yes it IS a case of differing opinions on what determines real world usability. My opinion happens to differ from yours.
And NOWHERE did I say a specialized tool has no place. Find it, find where I expressly said that. Find where I said a specialized tool has no use. of course it has a use, BUT only to the people that need it.
Do I have need for a set of whitworth tools? No. Are they specialized? Sure. In the case of some of those little linux ditros, they are specialized for certain things that only certain people need.
So now, maybe you can stop trying to read into this what you want? I feel as if I have made my opinion on what I feel "real world" usability is, perfectly clear.
As terry would say, you are starting to sound like a nitpicking wife.

I really do not care to continue to debate opinions on what "real world" means. I have my opinion and you have yours.
I also know what an OS is and does and yes, virtually any software add is considered an app. Ms bungles it, Apple does, all versions of linux do(just different amounts) too. The difference is that in the larger installs, they are already there, I don't have to add them myself. I don't have to install the system and then go out and try to dig apps up from a repository to add. An analogy would be that the small linux distros are that specialized clutch nut socket and ms, mac, larger linux distros would be like a whole toolbox with all the commonly used tools.
