GoPro HD arrived from the states the other day so chucked it on the car quickly and did a test 
Did not get charged import tax/VAT (woot) so it came down a whole £100 cheaper than UK pricing. For £200 I am mighty impressed by the video quality. Audio is leaving a little to be desired at the moment but I do need to have a good fiddle with it.
The quality of the unit as a whole is pretty good, it looked a little plasticy on videos but the rubberised plastic they use has a very nice finish and it feels much more 'solid' when it is in your hands. I was a little weary of the suction cup at first and I wanted to make a tether but was unable to find anything soft enough to avoid destroying my paintwork so I thought "sod it" and whacked it on the car, pulled it and shaked it around a bit and that thing is going nowhere. The only one incident I found of it falling off was from someone who put it on in the morning, left it on for some hours un-used while the ambient temperature rose and as a result lost suction strength. Needless to say I was checking on it every minute
I was very impressed by the cameras ability to maintain exposure in bright sunlight without going totally crazy and it did not stutter or glitch once.
Instead of uploading to YouTube I thought I would offer anyone who is interested in one the RAW footage from the cam, it weighs in it 1.3GB and is not the most interesting of captures ever seen but it will show you the quality of the video and do it justice without compression and resizing.
