This product would solve the isolated pools of storage issue: each home computer could use the NAS device either as primary storage or could back up local storage to the central storage server. It would solve the issue of central storage not providing offsite backup. It would come with a low enough initial price point to make it an attractive alternative to potential users, thereby leveraging price elasticity to increase volume; this would enable the vendor to increase market share, perhaps enough to dominate the segment. Moreover, once someone is tied into a particular system, they're likely to stay loyal. I mean, once you've got a secure place for your vital personal data, you're not likely to move it somewhere else: the switching cost would be prohibitive. And from the point of view of the vendor, this long-term commitment through high switching costs would be a bonanza. In effect, the machine would represent an alluring entrance into an extended annuity subscription stream.

So there you have my modest proposal to solve the home data center problem-a problem that is only to become more acute in the future. It's a problem waiting for the right creative solution.
