That is exactly what I wanted to know, thank you! This is an amazingly helpful place.
The Kindle wasn't an option, as I'm in Canada. The BeBook also attracted me, but I've actually seen a Sony 505 in the Sony store in the Eaton Centre, and I played with it a little, and really liked it. I am SO looking forward to getting one.
I've been systematically paging though the ebook index here, and I have a little list of books I want to download.

Well, make that a large list ... for me, one of the attractions is being able to read long out-of-print, but non-classic books which are only available for insanely high prices as rare editions. Suddenly, they're available for the downloading! Wheeeeeeee!
The hard part is going to be waiting for the reader!
I can amuse myself in the meantime by checking out the Toronto Public Library's ebooks, too, as well as downloading.
