I don't know why I said snowboarding, I'm skiing so will be attaching the GoPro to the end of my pole as well as helmet and chest.
I'm not sure where we are going yet, last year myself and friend went to Sauze d'Oulx in Italy for a week and it was fantastic, I'm trying to get more of my mates interested this year.
I'll look into a second battery nearer the trip, the supplier I bought the camera off didn't list any but the camera is only been out a week.
Regarding the PC, is it worth getting a SSD just to load windows and other programs on and then using a normal SATA drive for bulk storage?
