From 19 Minutes to 3 Hours

I got my new 4 GB Memory Stick Pro Duo today in the mail from Buy.com (who I guess was the vendor that Amazon.com selected for me?). It only cost $16, and now my sister's digital camera can hold 1319 6-megapixel pictures instead of the previous 120 or so. It can also hold a little over 3 hours of grainy digital camera movie footage, as opposed to the 30 or so minutes her previous camera could hold. The size of the old card, btw, was 512 MB, so I upgraded by about a factor of 7 or so once you take into consideration the unusable space that renders a factor of 8 unrealistic.
