I have to say I've become so used to conducting day-to-day business from a mountain that I'm starting to wonder why I need an entire office. A laptop and an Iridium sat phone are all you need, and of course a way to keep them powered. Brunton's portable solar panels are somehow able to suck enough energy from even the most overcast days to power the phone and laptop. These panels do away with the need for a loud generator and are the only option if you're backpacking.
