UPDATE: since the iOS 4.2 update, Apple has changed the power limit for third party accessories from 100ma to 20ma, rendering the card reader below useless. Thanks, Steve!

I needed a multi-card reader anyway for my iMac because it was getting cumbersome to look for the right cable every time so I got one as well as the iPad CCK.

And it works. Also with RAW files, well at least the NEF my Nikon creates. Just like advertised in the video.
