You find that so difficult to believe, VR? I only downloaded a couple of their free "classics," and that was mostly out of curiosity. I suspect that most folks didn't download them -- most folks seem to be interested in newer stuff. Perhaps a side effect of being forced to read "classics" in public school.
On the other hand, I've actually bought more books from Sony's book store than I thought I would, probably about 20 or so -- not nearly as many as I have from Baen. I tend to get things from Sony that I don't expect to
want to read again later (so I won't be bothered if they're not
available for download again later), and I find the convenience of getting them pre-formatted in BBeB is nice (I can usually read them on the L setting
).
