Shooting RAW files gives you lots of flexibility in post-processing, but they don't half take up a lot of space on memory cards. Typically, a 2GB card holds 100 RAW files for my D200. For day trips, I've enough memory cards to get by, but for longer trips I need something else. A laptop is one option, as would be something like the Nikon Coolwalker or Epson P-2000/3000/4000. However, I found the Thecus N1050 "nano" 2.5-in drive enclosure together with an 80GB Fujitsu drive on offer from Scan. Having used it in anger a couple of times, I've now got a good idea of it's pros and cons.
