I wonder why that file extension is called nib or xib.

I guess that the ib in nib is Interface Builder.

But the n? Or the x? Any idea?

nib stands for "NeXT Interface Builder", whereas xib is for "Mac OS X Interface Builder".

I think the "n" would mean NextStep, the "x" was added to indicate the new XML based format.
