"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!"
One thing that the LG offers that no other does - or currently plans to: 1080p/24 for BOTH HD-DVD and Blu-Ray. Upcoming releases offer this for Blu-Ray only with 1080p/60 for HD-DVD. This isn't an advantage for most, but it is for some.
