You're right but you've got it backwards. Today it will be 250GB, tomorrow it will still be 250 and also maybe a year from now, then they'll bump it to 500 but it won't be enough of a bump, because general web usage by then will use so much more data, what with Video+VOIP ubiquitous, collaborative working environments, many more societies depending on bandwidth donations from users to support their operations (ubuntu seeding for example), the list goes on, bitflation will never cease, just as this metaphor's counterpart, currency inflation, will never cease. We keep printing more money, and minting more bits (to an outside observer, it may look as though this is our purpose on the planet)

    But, the bits, like the cash, are inherently worthless, it's what they represent that matters, the collections of them, and in what permutations, and as Moore's Law continues to increase the number of bits we can process per second, we will inevitably use more bits in our endeavors. By setting tangible quantifiable limits on this moving target, you're building a damn far down stream, the reservoir will take some time to build at the bottleneck
