When I bought my Power Shot, it came with a 4G memory card. I had no idea how much that would amount to in pix or video. I found out last night video that for video it's about 40 minutes. I would prefer maybe a
6G memory card. My wife has been looking at them on the web and has found they are rated by levels or classes. What do these classes mean in terms of speed?- posted
