Gopro has release an updated version of their camera called Gopro Hero 2.
Since I already have an old version of the gopro HD I’m not sure if it’s worth to upgrade. It’s a bit pricey too.
Anyhow, it has an 11mp sensor, twice as sharp glass lens, some more output connectors and wifi support. It still captures only 30 fps@1080, so for video footage there aren’t much improvements. There is no composite video output either, which might be troublesome when used with some video tx systems.
