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!"
um 25 GB is bigger than hd dvd so whats your point, and newer big releases will get the 50+ GB discs in due time so? but 4 k wil need something bigger and a higher bitrate than bluray can currently offer.
also bitrate extremely important. why have something too compressed? no one wants download quality crap
