It's an interesting situation here, cause the Kindle 2 costs $350.00 or so and thus is price competative with really accessible devices like the Victor Stream and the newere PlexTalk pocket. of course those require usb download from a computer, but provide access to a large variety of books in non-proprietary formats. The kindel is WYFI and thus provides instant gratification, or nearly. Even presuming the Kindle were made entirely accessible via speech, It may be a tossup which would really provide the best bang for the buck. And, of course, you pay for each book with the Kindle.
As a total bat, it seems silly to spend lots on the fancy Kindle display, although if they had large fonts, low vision folks might find it very helpfull. A rare situation in which it might turn out that devices made for the bat market could actually be price competative with "visie' market stuff. Tom Fowle
