I'm not sure; Amazon putting data centers in glaciers or Google trying to float a ship out into the ocean to water cool it certainly seem like they could could provide either performance or prices an order of magnitude greater than what is currently available; the tricky part is building up enough steam that you can be trusted with enough cash to make that happen.

If nothing else, we all benefit from the prices. AWS is so cheap I barely have to think about it.

I mean when I think of economies of scale, I would name datacenters pretty high up on the list!

Thing of the googles and facebooks making their own servers instead of buying from off the shelf guys...
