Well, yes, but look at it this way:

I have about 25GB of music. Over my lifetime, maybe this will increase to 75GB. As my ears are unlikely to do anything but degrade (and I'm currently happy with my normal/high VBR encodes) I don't see a problem with (in theory) putting a definite maximum HDD size limit on *this product*.

A future box could do video, holograms, whatever, and would need more disk space - but as the quality is fine, I'd have to quadruple the size of my music collection to be running out of space in 100GB in an audio-only player - and my collection is larger than many people's.
