Hey everyone, I'm brand new to the 770 - just got my first one yesterday. So far it rocks. I have a couple of questions:

1) What memory card upgrade (if any) should I purchase and why?
2) I've been reading alot about partititions and file formats etc, but would appreciate a simple explanation as to what this is all about.
3) What are the 'must have' applications out there?

If any of you longtime users can help me out, I'd be very grateful.

Regards,

CW
