"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!"
Yeah I'm in NYC and RR Turbo is currently 15/1 while standard is 10/512. PowerBoost goes up to around 20 but I've never seen those speeds besides in speed tests.
