I fit into the "older woman" category, but I'm not a fan of piracy. This is mainly because you never know what you'll really get. I used to do a lot of Napstering, but the quality of most of the downloads were exceptionally poor. Now that it's easy - and cheap - to buy MP3s from Amazon, I'd much rather do that than bother looking for it free elsewhere.
Unless I were already familiar with a book, how would I know that the text even matches that title? I have a reasonable expectation of correctness when I purchase an ebook elsewhere, and with Amazon I can even get a refund if the formatting is poor.
I'll stick to buying my ebooks, or borrowing them from the library.
