I don't have an iPod, but I've been seriously looking into lightweight cameras and even video cameras. There are quite a few still cameras out now that offer 5 – 10 megapixel resolution for around 5 ounces. Not an UltraLighter's dream, but it's getting better than it was! A couple of years ago any 5 megapixel rig would weigh at least 5 pounds!
If you're a shutterbug like me, it's becomming more feasible to take a good camera along. I'm learning how to jettison weight by reading these forum posts and BPL articles, but one of my pack requirements is some sort of camera. My business involves taking photos and videos so combining what I love (hiking) with what I do is always a challenge.
I'm curious, what would some of you more experienced hikers advise me to look for/ be wary of in a camera for the trail? Goodnatured flaming of this newbie always happily accepted :-)
