This will probably only be useful to the serious hardcore mobile bloggers. I ran across these bags a couple months ago. They were a little pricey but i figured i'd buy one and check it out. I'm usually pretty skeptical about something that sounds awesome, always a catch to be found. These bags don't have a 'catch' yet. They are made with recycled plastic bottles, and are prewired to give you the ability to plug in all your battery operated hardware, like cameras, phones, pda, for recharge. It will do a laptop but it takes a while to charge. Personally the bags seem to be completely worth it for the blogger that is out and about. Check them out if you get a chance. http://www.solarpower-home.com/solar-bags/
