Re: Limited bit rate?
People get excited about access to lots of music in a convenient, portable format. Quality hi-fi gear is a niche interest, and thus there's not a lot of incentive to cater to that market, other than to mug them for more of their disposable income with nonsense products.
Beats is successfull because their products are fashionable, not better than their competitors - a good fit for Apple, I should think.
I can't remember when I last listened to a CD - everything is streamed from Deezer, via my phone, hooked up to the car stereo. The quality may be terrible but 1) I can't tell (I don't own any premium hi-fi kit, and never have), and 2) I don't care.
