The real problem is that there aren't many small form factor CD players out there at an appropriate price. If you want a small CD player to sit on an office desk, bedside table etc., you're stuck with one of the following:
1. A high-quality PCDP, most likely used and possibly difficult to come by
2. A craptastic half-wide DVD player mated to a DAC
3. An audiophile grade half-wide CD player in $500 land
I've run a few searches, and half-wide DVD players are generally the brands you'd want to give away but never keep for yourself. I doubt they'd be trustworthy as a transport. Same goes for pretty much all currently-produced PCDPs. Finally, there are only two half-wide cd players that worth giving a damn about, and they are far more than most people will want to spend: The Shanling PCD300A ($500 US) and the Musical fidelity X-Ray, which goes from $500-700 used on Audiogon.
I suppose that now that everyone in the world is listening to their emm-pee-threes, the average consumer has no need for such a device.
