"The average U.S. household spends some $5,000 
per year for their combination of cable, telephone, broadband, 
and cellular services. The typical family wireless bill often 
exceeds $200 per month."

That doesn't sound right to me.  The average U.S. family has a pretax income of $51k/year last time I checked.  They're spending $5000 of their after-tax on connectivity?  I don't spend anything close to that and I feel like I'm doing pretty well for myself.
