Apart from the option to shoot in 1080p, 960p, and 720p in 30 and 60 fps (720p) - which is a quantum leap in image quality - the new HD Hero comes with a rechargeable lithium-ion battery with about 2.5 hours' life, which is a step up from constantly changing AAA batteries to keep the thing running (annoyingly the AAAs would discharge in no time at all, even with the camera turned off).
Arabella's first sail of the season is tomorrow, if the weather gods remain in a benign mood, which is likely to be before amazon.com deliver the new camera. But if all goes well, and the HD Hero lives up to its hype, footage will start appearing in susbsequent posts.
