Thanks for the post Luca!
I ordered one to keep in the camera bag. I currently carry a 160gig USB powered drive, and use it all the time.
Like this weekend Cindy and I had to shoot a wedding and between the ceremony and the reception, we had a few hours to kill. We sat in the truck and cleaned all the cards with the laptop onto the little externial hard drive so we'd have plenty of room and free cards for the reception.
This is much cheaper than buying one of the Epson portable harddrives that cleans the cards. I was on the fence to get the 80gig one, but it's the same price as another body, which I'd rather have. I think they're going for $600 right now
This will be a great back up and a good way to carry much stuff with us when we go away on weekends and dont want to carry too much stuff.
I especially like the retractable cord as the one I have right now doesnt have this and wrapping the cord around the body makes the footprint larger. Everything has its payoffs right..LOL
