Hello everyone! I thought I'd better come here first before I make any big mistakes.
I'm giving my mother my PRS 600, which I love, and getting a PRS 900 for myself instead.

What I want to know is:
Is there anything I need to watch out for in deleting some of the books from my old reader while keeping others on it for her to read?
Will the 900 sync smoothly with the eReader Library I have now, transfering the books and notations I created on my 600?
Are there warranty concerns I need to know about?
Thank you all for being here!!
