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!"
I think its great that Sony and the other Blu-ray/ HD DVD hardware manufacturers continue to provide firmware upgrades. That way, even though they do pay more, early adopters don't feel screwed every time a new model comes out.
