Let the hive mind of Engadget get that for you.
"I need help! I want a small pocket camcorder but I'm not sure which one to get. I don't want to fall into the hype of the Flip because I worry two hours won't be enough. What should I be looking for when considering a small camcorder and where can I get a good quality one with expandable memory? Thanks!"
@Ted: Eh, did you actually check the internet? Many providers provide HD downloads (or should I be ashamed now for knowing?), on Bittorrent its HD porn galore. And because more and more people give preference to shorter clips instead of a full movie length for their porn, also more and more people have the bandwidth to be easily able to download it.
OK, if you live in a high bandwidth deprived area AND like full movielength, you might consider optical discs. But that will not a market big enough to decide this format war.
