Going on vacations without a lot of memory cards or a laptop is a really big mistake, so i bought a CompactDrive PD70X from eastgear.
The device came with a set of 2500mAh batteries from Sanyo, and a car charger. It is really small and is fast.
You can use it with one hand if you attach it on your belt with the provided case.
I put a 40GB disk inside and we are ready to go. No more laptop to unload my memory cards and i think that now is the time to start shooting using raw only.
