Who would WANT a gigapixel camera? (Score 1)

As a fledgeling photographer with a 6 megapixel slr of my own, I have to wonder...who would want a gigapixel camera? That Kind of resolution isn't too practical for anything other than being WOW'ed by enormous fine-art prints. I think the main issue, of course, is hard drive space. How many warehouses of RAID arrays would you need to contain your photo collection? "There are fields, Neo. Vast, endless fields... where photos are not taken...they are STORED"
