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!"
The only cool thing I saw on there was a portable copy. Does HD DVD do this?
It's in the spec, so yes it can be done, just isn't implemented in any movies yet. Even Sony's version requires a PSP (*yawn*) and I believe is only for movies that support it.
