The concept of paying for long distance is disappearing slowly, and someday there will no longer be any toll-free numbers. That's because cell phones, which usually include long distance, have become so prevalent.

Almost 1 in 3 of us exclusively uses a cell phone. That's presented a problem to government organizations like the CDC that rely on an ever-shrinking sampling pool of telephone users for surveys.

Of the 30% of us that exclusively use a cell phone, about half of us have a home landline but never touch it. For too long, landlines have been shoved down our throats if we have DSL or antiquated burglar alarm systems. But your monopoly local phone company's day in the sun will be over when the Clearwire initiative happens. Meanwhile, your alarm company can usually install wireless monitoring -- that burglars won't be able to cut -- for cheaper than the landline option.

In related news, cell users may have noticed that spam texts are an increasing nuisance. Americans will get 1.5 billion spam messages on their cells this year, according to Ferris Research.

The cell carriers make a cut of the profit each time a spam comes to your handset, unless you're on an unlimited plan. Clark gets about 2 of these a week, but he's already gone unlimited.

Cell carriers would be wise to switch everyone to unlimited plans. There are virtually no infrastructure costs, and the price of not doing so may be people completely shutting off their text messaging out of frustration.

Clark also believes a financial deterrent might rein in the carriers. If they were charged double -- 40 cents every time you dispute an errant spam text that costs you 20 cents, for example -- that might straighten things out.
