I have read just one DTB since getting my Kindle... and have been buying Kindle version of books i already have read if I want to re-read anything (well, if they are avialable). I find it a lot harder to read DTBs now... I do have a few I haven;t read yet, and aren;t available on Kindle - so I will eventually get to them in the DTV... but won;t be as easy or convienent as reading on my Kindle.
