I think of the essence here is the idea of universal connectivity, and I would pay 10 bucks for that easily. Imagine this translated to a daylight-readable tablet or notebook? You can have access everywhere, use it as a GPS device with maps loading as you go, reading books or doing work regardless of lighting conditions, and so on, and best of all, not being limited by your particular network. It just "grabs" the fastest available signal and runs with it. All this being valid for world travel, not only your country.
That would be the vision I would subscribe for.
