For those of you who might be interested, there are a couple of Gene Wolfe titles in PDA format, published by Peanutpress. The titles are "Strange Travelers" and Return to the Whorl". The prices are somewhat discounted from the paper editions, but not by much. I downloaded "Strange Travelers", which I had not read, and have been surprised at how enjoyable the e-book reading experience has been. I'll probably soon download "Return to the Whorl", just so I can keep it close to my heart, where it already resides in spirit.
Anyway, to keep this posting from sounding like an advertisement, I won't give you the URL for peanutpress.com, but it shouldn't be difficult to find if you want to check it out.
