And what will the iCloud run on?
Sure the consumer disk industry is probably on its way out but someone has got to buy hard drives to store that data on at some point whether it be the customers or Apple/Microsoft etc. Besides, spinning disks have been on their way out for some time now even in PCs and laptops.
