I'm not a fan of this. I'm 13, can't get an iPhone, have no reason to get an iPhone, but I like iOS, and the iPod touch seems to be on the chopping block as more and more kids just get iPhones. Even Steve Jobs said that the iPod touch was just training wheels for the iPhone, and so when kids just get iPhones instead, the iPod touch is basically selling 0 units. So....If the iPod touch doesn't survive until I get a driver's license and have a reason for a phone (GPS plus contact with my Mom) I'll basically be boned. I'm not really angry with apple or saying that they should keep the iPod touch for 1 person, I'm just saying I'm kinda screwed. And also iPods are just generally cool, I love the things for some reason.
And I think that the iPod Classic can really only be discontinued if they bring out a similar capacity iPhone or iPod touch, my Dad's entire music library doesn't even fit on 64GB (He has tons of albums, and also 320Kb per second files) so really the only thing he CAN use is an iPod classic.
