From a non-audio standpoint they are VERY overpriced in my opinion. Closed source software. Inaccessible batteries. Having to convert anything to play on it. Limited app choices.
There are better droid options for phones and tablets. And as someone who does publishing and design work for a living I have never understood why Mac is preferred over PC. I am in a minority though. It's not that Mac is "bad", but it brings nothing to the table imho and costs so much more than a PC and creates too many limits.
Now, I don't do Apple, so maybe they sound great
But whenever I see people with all their Apple products I feel certain they have been heavily influenced by marketing just like the beats buyers. At least their apples aren't junk, but they paid out the nose to do less than I can do for cheaper.
In Spade's. You forgot to mention closed architecture as well. Need more storage in your ipod, well buy a new one. No SD slots or usb connectivity. Same old apple song (and I have dealt with them since they existed) our way or the highway. They are systems for people who refuse to plan ahead.
