Ken, I think you are wise to look at alternatives to ebooks.
I have just started testing the idea of giving my customers the option of receiving a CD in the mail at no additional charge.
Why? I think ebooks are on the decline -- too much low priced junk out there.
I have noticed a downward trend with free ebooks as well: People are just not reading them. I know this because I track clicks on the links in my ebooks and they have been steadily declining.
