"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!"
Phoenixxx1974, HD DVD only mandated at least 128Mb persistent storage compared to the 1Gb in profile 2.0. The use of Java also better for content too. So if you must have internet connectivity (as every PS3 is shortly about to receive), you'll have a far better experience in Blu Ray than in HD DVD. It even means in theory that you could download full movies or TV shows and not just trailers. I think profile 2.0 is optional so we're going to see a mix of 1.1 and 2.0 players for some time yet. Take your pick.
