Thanks to everyone for the greetings.
Elsi, I thoroughly agree with your comments; the Sony & Kindle sales models are quite similar, and that's why I didn't get a Sony either. Both the Sony and the Kindle (esp. the Kindle 2) seem like very nice hardware devices, though, and I've been keeping an eye out for changes in the DRM handling.
Is it really true that Amazon was a leader in DRM-free music? I didn't get much into online music purchases until this past year, and ended up signing up with eMusic. They sell only DRM-free music, but I don't know how long they've been around or how long they've had this policy. In any case, though, Amazon's choices here are welcome, and along with you, I really hope it spreads to eBooks. Early in my investigations into eBook, preceding my Cybook purchase, I ran into Baen (
http://www.baen.com), who have been pushing the idea for quite some time.
As to what non-fiction I read: Mostly science fiction, with a preference for "hard" science fiction, which I define loosely as science fiction with a plot that is driven or enabled by extrapolating from plausible but speculative scientific theories. Also a bit of fantasy (hard to find ones I really like these days), the occasional historical novel (loved Shogun when it first came out, but that's long before eBooks), an occasional spy thriller. I've been taking the occasional dive into the Gutenberg collection and have came up with, for example, the original Sherlock Holmes stories and H.P. Lovecraft's novels and shorts.
