Free versions of classics are the best
I bought a Sony reader and got a "free $100 in "classic" books" offer. Everything in the list is PD stuff that's available from Project Gutenberg. I had a peek at a couple of Sony's editions on a friend's reader, and they were totally uninspired. Cruddy formatting, clearly just slurped down and dumped into a LRF file (while adding DRM to a PD work!).
I went to mobileread.com and found the same collection and hundreds more, all lovingly formatted into various formats by volunteers. All free, and of much better quality than what the commercial places are charging money for.
My fear is that someday they'll get something written into law giving them "temporary" ownership, or at least format-specific rights to, PD works. Then of course they'll get those rights extended until it's essentially permanent.
No interest in Kindle, if for no other reason than that Amazon seems to be trying to corner the eBook market, and I'm not interested in helping them. Since they have eBook rights, if they started providing downloads in other formats, they might start getting some of my money, but they're locking everything up in Kindle format.
