That's a respectable position -- everyone has different tastes, and I'm glad you didn't pay for something you didn't want. "Try before you buy" is the beauty of shareware anything, ebooks included.
Incidentally, if any other authors are reading this and would like to give the shareware model a try, please
get in touch. Maybe you have out-of-print titles which are unlikely ever to be republished, such is the state of the industry; or maybe you are an established author whose work is now rejected by publishers not because it's bad, but simply because they don't foresee the massive sales most of them seem to be chasing these days; or maybe you are a talented newcomer who is finding it impossible to break in. Whatever your circumstances, the e-reading market
might offer an opportunity.
At the moment I feel like a voice in the wilderness, and am keen to help others who might want to release their books as shareware.
