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!"
You know, adding this to the spec doesn't mean that it'll work in current dual-layer drives. The BDA could approve the 100GB quad layer discs that have been demoed too, but it would be the same story. Until triple-layer compatible drives become widely used, the 51GB disc is useless.
