Personaly for my storage solution, I plan on buying an Ipod, Iriver, or one of the Dell Jukeboxes and buying one of the CF Readers / Transfer dongles for it. I know its slower than a dedicated unit, but I want the functionality of having the music plus being able to store my images, on the days I do fill up the cards (Curring I just have an 128mb and a 256MB CF cards) on my *istD they dont last long when shooting in RAW....
I personally have been looking at going with the smaller size (1* vs 3*) but keeping it RAW.
