I'm glad you were able to recover your images. Losing images in "the
old days" meant fogging the film or some other clumsy handling on my
part. Adapting to digital can mean some unexpected challenges, but
hey, you got 'em back!
As for backing up your camera... there are a bunch of devices that
let you download cards to them while you're away from your MAC. Some
are specially built for that purpose and can get a little pricey, but
they also have decent LCD screens for reviewing your shots "in the
field". Maybe the simplest is a gizmo that lets you use your iPod as
a storage device via a card adapter that plugs right into the bottom
of you iPod. You may still chose to leave the images on the card, but
at the end of a day's shooting, you can back them up to the iPod or
on of the other storage devices. Here's a link to a bunch of them on
Amazon: http://www.amazon.com/tag/digital%20photo%20storage
