Uhh, am I missing something? This is all well and good but when did the “cloud” become an unlimited, always renewable and expandable resource like “green” energy resources? The cloud is made up of finite, physical servers that carry a cost. While that cost might be financially feasible for those companies to bear right now, I doubt that it will remain that way forever and expand. Somewhere down the line the break-even point will be passed and then someone other than the owners/maintainers of the cloud physical resources will be forced to pay. Forced to pay? Yes, because once a person, business, or organization has moved it’s data storage to the cloud they will be invested deeply enough to make it painful to try to take it back and maintain it on their own. This is like outsourcing your critical processes and operations that are essential to survival. Once the outsourcers have you they can then ask any price they want or put whatever restrictions they want on THEIR services because they know your operation no longer has the people and infrastructure to take it back. The cloud can be a great resource but there are big and potentially painful risks involved as well.
My guess is we’ll see continuing unlimited offers coming. You can get a 1 TB disk for $50 retail; in bulk, probably less than $40 each. That 25 GB storage is just $1 cost for HDD.
They’ll make money on ads or selling you services - like Microsoft offering unlimited storage for their music and productivity tools. Use their tools (pay money), they’ll toss in storage online for free.
