I was pretty excited when this first appeared, but alas found no satisfaction with my cheap Sony Cybershots. They do a fair job in the usually low light shows I tape. I have multiple batteries, and get a bit over an hour on one.
But man do I keep busy, because in addition to a main camcorder, I run up to four of these Sonys at a time, and they shut down after @ 29 minutes recording. So I'm constantly running around (through crowds at times) checking timing, and batteries. Ugh.
