Sorry if this has been discussed elsewhere. I was looking at the D800 at B&H the other day and the lass behind the counter told me re: the larger image files - that folks who bought the D800 had to upgrade their storage and processing equipment, new cables etc. Is this true? Is this your experience. I'm using a MacBook Pro about 3 yrs old, LR3, CS5. Thinking of working with an external terrabyte soon. I'm an amateur but would love to upgrade from the D700, but cannot afford a new computer as well.
