Need more input - Which Sony Cybershot?
I've owned one - the Dsc-P1 3-megapixel.
Nice camera - sold it to upgrade to a Nikon 8800.
for specific camera details.
Personal Opinion: I try to limit the types of media I have around - If you already have a Sony that uses memorystick media (laptop, Mp3, PSP, etc) - having another use for memorystick is great.
