Hmmm. Yes, somehow my .signature disappeared. Thanks for pointing this
out. I want those links getting around! <grin>

No. The digital talking book standard is media independent on purpose.
Early implementations of the standard use CD ROM. Future ones may go to
DVD--there are good arguments for it, but no one has committed to that,
and NLS specifically wants to go to some kind of reusable static memory
device. So, get a DVD if you like, but don't expect any digital talking
books on DVD any time soon. Meanwhile, if you choose CDR, you can always
get DVD later. I think both the Thinkpad and Tekra use swappable devices.
One interesting option, which I have and like, is to get a CD writer. It's
useful to be able to create a CD for someone.

Yes, I have the Thinkpad T20 which has now been replaced by the T21. I
believe the 21 has the same Crystal Sound cs14/22/24 chip which is
multi-source capable.

PS: I think it sounds pretty good even through the native Thinkpad
speakers. Bill Acker has a Tekra and hates the sound. So, you might want
to do a side by side, if you can.
