Be carefull if you have a mac... I have a mac book pro and the go pro has major issues pluging into it. so i have to use a card reader which works fine, but the format i think m4v doesnt work on mac to well, Imovie will handle it but final cut express/pro wont accept it... And at least on mine, you have to take the battery out and put it back in to turn it on, and sometimes it will only record for 5 seconds.. Otherwise its a great camera with great footage, but a couple bugs, that for me, make it usless sometimes. I do plan on returning it and geting a new one however.
