Does anybody backup their cards right away while in the field? Took some awesome pics today, but would not have been too happy if the card had been damaged or lost/stolen before I got a chance to put the pics onto my MacBook. How do you do it? Tried to backup my card to my windows laptop I had with me, but it ran out of battery since I forgot to charge it... Maybe thinking of a NetBook instead just to throw the pics on there in case the card gets lost, or the camera with the card in it gets stolen. Thanks for the advice!
