Am I missing something?

It seems that there are two trains headed towards each other at very high speed, and folks seem to be pretty excited about getting on one of them or the other. To wit:

On train #1, we have "the cloud". We're told that we don't need to worry about little things like disk space, storage, or (in some cases) ownership. All we have to do is upload our documents, music, videos, photos, and applications to the invisible disk drive in the sky, and they will be waiting for us, whenever and wherever we want them.

On train #2, we have the coming end of the unlimited data/download plan. Here's a challenge for you- go find a cell phone/tablet plan that gives you unlimited wireless data. I'll wait. You can't on AT&T, T-Mobile, or Verizon. Sprint technically still has one- but the CEO says it depends on "usage remaining reasonable", and Sprint's network in major markets leaves something to be desired regardless.

For now, your home internet is safe. But what happens when the cable operators start seeing people "cable-cutting"- or canceling their cable service in exchange for Netflix, Hulu Plus, and whatever new streaming service lurks around the corner? As a gigantic portion of homes receive internet service from exactly one company- the same one that provides their cable TV- one would be foolhardy to assume that said company isn't going to replace their lost revenue.

Something's not quite adding up for me here. I think I'll keep my hard drive for now.
