By 2010, it is estimated that nearly 3% of the capacity of all digital storage media (hard disk drives, flash drives, memory sticks, the lot) will consist of photographs and video clips of the London Eye. At this rate, we'll have to start deleting medical records from The Spine just to make room for holiday snaps and wannabe artists' works. Which will be no bad thing (ooh! Bit of politics there!)
But well before then, in fact just now, the first mass-produced terra-byte hard disk drives have reached the market, so we're safe for a while yet.
