I was looking into one of those for my upcoming overseas trip, but from the reviews on the Apple website, it sounds like it's a real pain in the neck. Instead, I purchased new CF cards (2 2Gig cards), figuring I could shoot JPGs and have way more than enough space, so I wouldn't have to bring my laptop to download for the 10 days of the trip. Plus I needed new cards for my motorsport shooting, so it was the best option for me.
