John, I have an 8GB SDHC in my camera and it will hold 2 hours of HD video...Mine was had for about $15, and if I happen to fill it with usable video, I can always put that in the computer. If someone is so into video recording that they're filling memory cards, itwon't be a big deal for them to pick up a 500GB external hard drive or something for their storage. Really, other than long vacations, 1 memory card in an 8 or 16GB size would be all that was necessary. I've certainly never had a need for more than 1 card in my camera...then again, in terms of 10MP stills, I have room for over 2000 on my card.
