Two ways to get cancer

Erinn Clark implies that a cell phone habit is more expensive than a cigarette habit. The numbers are a bit different here:

New cell phone: free with annual contract
Nationwide coverage (600 minutes/month): $40/mo - $480/yr
Total: $480/yr - $40/mo

Pack of cigarettes: $7.50
3 packs/week: $22.50
Total: $1170/yr - $97.50/mo
