Good point: this is another "know what you want the camera to be capable of" issue. It's not been a problem for me since the D1's battery is good for several hundred shots when fully charged and I'm never away from a power source or a computer for very long.
Having sufficient storage to cope with an extended trip would be another issue: I've taken 300-400Mb worth of photos in a day on quite a few occasions....

Don't forget it cuts the other way as well: my 80-200mm zoom turns into a 120-300mm: very nice for photographing wildlife, for example.
