Personally, I find this sort of thing to be a perfect example of the 'I'll drag you to hell with me' syndrome. The music industry as we know it sees its demise, and it wants to get as much money as it can out of everyone as it slips down the series of tubes and, if this added cost makes the instruments of their demise that much harder to procure, well, so much the better.
That said, I can't help but wonder how much this fee would be. I mean, really, how often does one have to buy a music player? I have an iPod photo from 5 years ago that still runs like a champ, to say nothing of the -minidisc- (remember those things?) player/writer I've had for probably 10 years now and with the only problem being finding new, blank ones when I accidentally leave one in the pocket of a pair of pants destined for the washer machine. It'd have to be somewhat substantial, given that people don't need a new one as often as they do/did CD-Rs, assuming the industry wants to make the same amount they were before, let alone what it'd have to be if they wanted to make more. (Yes, yes, I know. Don't be silly, of course they want to make more.)
