These days it's more of a joke than anything. People who take it seriously are morons. He's had some negative things to say about the new generation of music trends, but his problem has nothing to do with iPods themselves; it's about the effect it has on the musician and the album and what they've brought, not the hardware or the company (arguably, anyway...I mean the iPod and Apple were
kind of the big bang for the paradigm shift in music). He's made a few comments on how it's become less personal and not as intimate as well as having a problem with the use of 'shuffle' in that it essentially negates the way an album is constructed; furthermore, the new emphasis on single songs instead of albums seems to rub him the wrong way as well as the 'way' it's become popular to listen to (I remember one interview had him commenting about him reminiscing, listening to an album in his room on vinyl, from start to finish and how that'll be an extreme rarity) and of course, like any other musician today, seems to have a problem with the age of music sharing, downloading, etc.
Sure, he's crotchety sometimes, but I can see why with how drastic the music industry has changed in just my own life alone. I can't imagine being born during a time when vinyl was the main format and seeing all the changes till now. It's not necessarily bad, but I don't blame him for being the grumpy old man sometimes.
Other than that, it's mostly people being people and blowing shit out of proportion and/or poking fun at it, which is never a bad thing (the latter, anyway). Adapt!
