I’m curious to learn more about oen of the key points of the blog, one that I’ve seen repeated elsewhere in discussions about online backup.

You highlight the fact that you think services like this should be “reasonably priced and without limits.” I’m stunned (still) to see so many people write this same thing. Why would any one expect a service to have no limits? There are very, very few services of any kind that operate this way, and most that do ultimately leave the unlimited plans because the are no sustainable.

Yes – certainly it is normal and understandable to expect “reasonable” pricing. But expecting a service without limits (to last) just seems silly, especially one that has real on-going costs (even if those costs improve with scale and improve over time). Are there examples of any services with variable cost structures that have had long-term successful unlimited offerings?
