Ipod Users Going Deaf? What?

Now, I'm not the Young brother that typically reads the Scotsman, but check out this article on Ipod and other MP3 players.

Now, I can certainly understand why you shouldn't listen to loud music for a long period of time. They say that any MP3 player can cause damage if set too loud, etc. This is all common-sense stuff here. What I don't understand is why they have to specifically point out the Ipod. They don't specify any other brand of MP3 player. Why not?
