Folks, as I keep saying, the issue is DRMed content. Your only choice is Sony's BBeB if you want to read best-sellers in e-book form--at least the vast majority of them. The Sony can't even do DRMed PDF. I know that a higher percentage of MobileRead and TeleRead readers than the population at large will read and love public domain classics and other mercifully nonencrypted works. But the typical reader will still want contemporary books from major publishers. What's more, the DRM and format issues are related. "Open" formats won't mean squat if DRM systems clash.
Meanwhile BIG thanks to Bob and NatC for all their hard work in sharing the details with us! - David Rothman (former Librie owner), for TeleRead.org
Will the Sony Reader be the Edsel of E Ink?
