There are three reasons to deploy wireless. You can't install wire, for whatever reason. Wireless is cheaper over a given time. Or you need mobility.

The data pricing trend is downward. We're expecting unlimited wireless broadband services in the $35-$45 range in the next year or so. There will always be a premium for wireless, but the objective is to get to the same price point as wired.

Reasons aren't really things that make you do other things. Reasons are things that you make up, much later, to reassure everyone that we are all logical and that the world makes sense. We do unreasonable things, because we want to, at the time. No reason. Much later we sit in the wreckage, building reasons out of little bits of wreckage, so we'll have something to show the crash investigators. Look, this is what caused it. So the whole mess at least appears reasonable. So we can convince ourselves that at least there was a reason for the disaster, something we can prevent or avoid, so it'll never happen again. But a lot of the time there's no reason. We just flew it to the ground. Because we felt like it. And we're still dangerous. And it could happen again anytime.
Its easier to live with each other afterwards if we give each other reasons.

There is no functional difference between a wire-based phone call and a wireless phone call, so they should be taxed the same way. Cellular providers have chosen to pass the tax to their consumers. They could have chosen to absorb all or some of the tax as a cost of doing business.

No matter what political reasons are given for war, the underlying reason is always economic.

It will be ubiquitous and a monster opportunity.
