I want to get a digital camera.Congratulations for you. Would you have any clue what to buy in one. I see things like 6gb,7gb, or expensive one 8gb? does it matter? I am technologically disadvantaged since my sons left home, and I have an important special event coming up.I'm already cranky because I didn't have a camera at the Zoo. can anyone advise me what to buy?....kind regards Jjulia.
