After research and good input on this forum, I am pretty sure I want to get the s90 as an "everyday," easy to carry p&s camera. My concern is - do you have to be a real photo expert to use it? If I hand it over to someone who has no photography experience and is used to only basic p&s cameras, will they be able to figure it out. I guess I'm kind of asking if the s90 has an "auto" mode and how good is it? Thanks!
