Obviously both of those numbers shrink a lot if you are recording. For most of the day (i.e. not right at sunset), unless you are riding deep in trees, the GoPro1 is probably good enough on its quality related to the lighting... and it is also a LOT cheaper right now. After our last time on the mountain with the GoPro2 dying on us way too soon, we decided to use it only for SCUBA from now on, and use the GoPro1 for snowboarding.
Again I can't speak for the Contour +, but I had the Roam out last saturday for about 2 hours. Since it's never in standby mode (just slide it on and it turns on and starts recording all in one) it only drains the battery when you're recording. I took 19 videos each about 5 mins long and when I got home the battery was about 50% when I plugged it into the comp. This was recording in the "tall HD mode" 1280x960 @ 30 fps. It can record in 1080p but it's upscaling to get that, and I wanted a good portion of the nose of the board in my shots for some perspective.
