I actually thought DH & I were unique in this, but he brought his laptop (has an iBook for work), and each day we downloaded the pics from the memory card to save on the laptop's hard drive. We ended up with over 250 shots for a five-day trip last December. We did pick up a (I think?) 128 mg card on sale, and that allowed as many pics as we could take in a day.
As it was right before Christmas, the Osborne Spectacle of Lights was up, and he just went nuts there - must have taken about 50 shots there alone.
The initial investment in the camera certainly does not make it cheap, but the savings and convenience thereafter is wonderful. Plus, I have a gorgeous sunset over the lake, taken from the window at the California Grill, as my computer desktop picture at work - Priceless!
We did not try to email; didn't bother with a net connection during the trip. There was plenty of space on the laptop to save them.
One warning - DH lost some pictures of AK and AKL because he thought the download was done when he cleared the memory - it wasn't. That was sad and a hard lesson learned, but it will never happen again to him. So be sure to check that you have all your shots saved before you clear the memory card!
Have fun!
