Re: OT Ipods



As usual, you mistakenly assume that it's all about you.

I posted this for the benefit of anyone -- you among them, but not only
you -- who might be interested in knowing the truth. I wouldn't expect you
to be interested in facts. You never are.

Rob, when you post stuff, have a clue first. Then people like me wouldn't
feel compelled to set the record straight for those who might accept what
you say as gospel. (Not that anyone would, in your case.)
