Ask Engadget: Which digicam takes the best video?

We know, we know -- a camera is only as good as the images it produces, but this week's Ask Engadget question revolves around an oft overlooked video function. (Psst... feel free to shoot over your own inquiry to ask at engadget dawt com, but only after you check out Jonathan's question below.)

"What's a good camera that takes great quality video for at least 30 minutes (yes, I know I'd have to buy an extra memory card)? So many of the cameras I've messed with have a limit on how much you can record in one session, even if you have enough storage space. Thanks!"

Here recently, a few cameras have surfaced with 720p video capabilities, and there's a plethora of options if VGA is good enough. What camera is best for snagging those candid videos that inevitably end up on YouTube / Facebook / etc.? Don't lead the man astray, now.
