The argument for ubiquitous internet is ubiquitous computing, a field in its infancy. The UX for continuous data usage is simply terrible. Once you change that, you can change the rest.

The N-series tablets are a great step towards it, but the rest of it requires hardware (such as eyetaps) that just aren't available yet. I could rant for awhile, as this was one of the foci of my MSCS.

To sum up, don't think in terms of the way you access information right now. Do think about the informational transports you use --- this is especially hard in the US, where WAN standards are quite crippled and deployment/pricing is terrible --- and imagine them replaced with one ubiquitous, high-speed, network.

Ford Sync, actually, is a great example of what I'm talking about, although it of course doesn't have any network access.
