The more I think about it, the more I think that it's the move away from the PC that will mark the next stage of the evolution of the internet; the idea of the internet was of connected and networked computers. The idea of the Web is all about interconnected and networked documents. The move away from the PC and towards other devices— a "Web of Things"— seems to me to be the next logical step.
The idea of the PC as the "hub" of your information is starting to feel a bit dated; as the number of devices that we are using regularly increases (mobile phones, laptops, netbooks, work PC, home PC), the idea of a central device that everything else revolves around seems to me to be an increasingly outdated way of organising your technology; it's too much to rely on. I know 2 iPhone owners who illustrate this point perfectly; one doesn't own a computer, so her iPhone is tied to a friends' PC (and iTunes account), so much of what I would call the important functionality (the ability to transfer files, download software, back up contacts lists, install updates etc.) is lost to her. The other owned a laptop until it recently got stolen, so there's no way for him to upgrade the software on his phone without first completely wiping it (and in the process, losing the music, photos etc. that he now has on his phone, but with no other copies.
