The original Flip is excellent in low light. I prefer it in low light over my Sanyo Xacti HD700, which is great in good light, but TERRIBLE in low light. I am excited to see whether the Flip HD's low-light claims are truthful.

Interesting, I actually have not played with one of these yet. Some of these small guys, like the Sanyo and the Bonica, have started coming along. Last year at BTS there was some good stuff with the recent Bonica...came very close to picking one up, just because it was so small (I had tried one of the Sanyos, non-HD, a couple of years back and it really underperformed, rented one for a couple of days, so it could have been the set-up.)
And if the Flip does improve on the low light, like some of the other smaller things such as the G9, it could be something to throw in the bag based on size, weight and cost.
Some of the video did not look great on the links, but it sounds like it does better than shown there from what you are saying?
