I am 500 user who was waiting to update to the 505, my reader was a present and only 1 1/2 yrs old..but of course with the 600 my 500 days may be coming to and end...although always nice to have a back up..anyone else persuaded to finally upgrade..? I love my 500 but more and more books are available pdf and epub..after 1 1/2 yrs I have over 600 books..so it is an understatement to say I take my reader everywhere....
