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'm an LCD owner, never had a plasma, but I'm skeptical that LCD is better than plasma at everything. Something like 120Hz just seems like a hack simply because the crystals just can't change anywhere nearly that quickly. And those sets are more expensive than plasma anyway.
Keep in mind that current LCDs lose brightness over time too. LCDs in general still use phosphors in the form of fluorescent lighting, and phosphors just fade over time. I say in general because there are a few extremely expensive LCD panels that use LED backlighting, but they are such a rare exception that they prove the rule.
