Good points...
Thanks for making the point about coverage. As a Canadian, I know very well how bad it can be when there are large areas with little to no coverage at all.
Sadly, for your second point, I just don't see something like that happening very much in the near future. To create a complete shift like that, requires a lot of coordination between different companies, and unless the companies themselves come to the same conclusions that led you to want some system like that, I can't see it happening for quite some time.
What I can see is more integration of cloud computing into portable devices. I could even see something where the device itself is only really a thin client for a cloud computing system. But heavy integration with the home system? I dunno, I think the solutions will be more cloud-heavy in the near future before they finally figure out a more direct way of doing things.
