Hey all, my apologies if this is a dumb question, but I was curious if anyone knows what iPod is the most power efficient for playing only podcasts that has at least 4 GB of storage. For power efficiency, I need whatever will take the least juice from a Mophie juice pack to recharge. I think that the shuffle is the most power efficient, but I don't know the detailed statistics about it. I'm preparing logistically for a thru-hike on the Pacific Crest Trail, and I'd love to have something to listen to podcasts on, mailing one of two devices home to have new episodes loaded onto it before I get to the next post office (if that makes any sense). Basically, I need something that can hold 1-2 weeks worth of podcasts (and I can listen to a lot!) but that sips power. The shuffle's lack of screen isn't an issue, but I think I'd want a larger capacity. If y'all have suggestions, I'd love to hear them. Thanks!
