Re: Go Pro - Skiing Holiday
I've had issues with my GoPro Black stop working if I'm using the WiFi. So turn that off, might last longer.
I use my Surface RT to offload all the images to a USB HDD. It has a build in micro SD reader and well being a windows tablet means I can easily do something like copy files.
However, I'd be tempted to just buy a few large micro SD cards. I mean you aren't going to have anything interesting 90% of the the runs, and you'll know it. So a few spare cards and just format them on the GoPro.

For cold weather there isn't much to be aware off. Even in -25C I had mine still keep going when all other tech around me was failing (battery life is shorter though!) - just don't open it when on the slopes, you will get some moisture in the case which will lead to fogging or freezing on the lens.
