I think that I will upgrade to either the 650 or the 950 and pass the 505 on to my husband, who has been eying it for months and hinting to me that I should upgrade soon
I don't mind paying full price - I never mind the expense when anything reading-related is involved. I really think that I'll treasure the dictionaries and the note-taking features. Especially the German dictionary, I'm trying to learn Deutsch! As I am more than satisfied with the 505 screen, I wouldn't consider the Pearl screen to be a reason for upgrading in my case.
