iPod the Kleenex of MP3 players

Xerox. Kleenex. iPod.

What do they all have in common? They are all brand names that have come to define their category, at least that's what this article argues.

Xerox and Kleenex certainly have transcended being a brand, but are people now calling all MP3 players iPods? It seems like the answer is yes, and is that a bad thing? Certainly not for Apple, though other MP3 player manufacturers might not be so keen on it.
