When I got my new Canon S2 IS a few weeks ago to my disbelief it only cam with a 16mb memory card so I bought a 512mb high speed card at that time. I debated about getting a 1gig card later but today I was shopping and found this handy 20gb portable hard disk for not much more money than a 1gig high speed card costs. So this weekend when I'm at the Petit Le mans I don't have to worry about pic size or filling up my card, I'll just dump the card on the spot and shoot away! The Inoi hard disk is about the size of a pack of cigs...very nice!
