I myself have many hundreds of CDs, and only a few albums in Hi-res (I never jumped on the SACD or DVDA bandwagon), but it wasn't really all that long ago that I had several cassette walkmans and a trunk-load of cassette tapes. I had quite a bit of vinyl, too...
But Hi-res will soon become the de-facto standard, as public awareness is increasing, record labels are seeing it as a potential shot-in-the-arm for their flagging back catalogue revenue streams, CDs are becoming redundant in the face of digital downloads (so resolution is no longer limited by the capacity of the optical disc standard upon which it is stamped), and portable electronics hardware is becoming easily capable of handling hi-res content. It's the way the industry is moving.
This isn't an argument for the supposed superiority of 'higher-than-redbook' resolution content, on a subjective psychoacoustic level. It's simply an acknowledgment that the audio industry is moving inexorably in the direction of hi-res. So although I don't personally give 2 hoots about DSD (or DXD, for that matter), I can understand why someone who's purchased some audiophile recordings in DSD might wish to be able to play them portably (capacity limitations notwithstanding). ...but, on the flipside, unless there is provision for at least 500gb of combined storage (be it soldered on the main board, or mSATA, or 2x fullsize SD), the provision of DSD support does lose credibility, anyway.
As time goes on, I currently anticipate that I'll probably be buying most of my music in 24/96, as it is a compromise in terms of cost and memory capacity, and I don't hear any audible benefit (at least on portable gear) going past that particular resolution.
I see your point about people restricting their listening based upon a narrow few available uber-audiophile recordings, Mim, and there's undoubtedly some truth in that - there's invariably a geek fringe minority in almost every endeavor in life, and it is rather sad (in both senses of the word).
But, for the rest of us, Hi-res will become increasingly ubiquitous, whether we approve of that or not, so why not buy hardware which can cater for it (within reason), if it is easily available?
