If you can afford, the it more CompactFlash space the better. If you're a mere mortal and go on roadtrips or shoot lots of large files then a digital wallet or laptop is a must. The further the trip and the bigger the files you create, the more important a larger storage device is.
Shooting RAW files with a D100 eats up space quick (51 images on a 512MB card). When a photographic opportunity presents itself you don't want to be running out of space. One disadvantage with digital cameras is that running to the drug store for more film is much more expensive...
i agree!...if money is no object then buy lots of memory card..but i think most of us can't...i haven't used a digiwallet yet...probably get one by the end of the year....hoping for price drop...laptop is always dependable too!
I have been using a Terrapin Mine since the beginning of the year. It has a 10 GB hard disk, with just over 9GB available for data. To say that this device is invaluable would be an understatement. It took me some time to trust it, and I still get a bit paranoid towards the end of a holiday, but without it I would have had to spend thousand's of pounds in memory cards to take the same amount of pictures. This is especially the case as I always use NEF, to give me maximum flexibility later on. So far I have spent about 5 weeks travelling with it and it has proven itself to be totally dependable.
Alhtough a notebook would allow review of pictures the extra hassle of taking it along is outweighed by the convenience of a small device, it fits in my camera bag no problem at all.
