Given the impact cell phones have had on auto accidents (someone using their phone in the car is about as dangerous as a drunk driver, statistically), I'd say overall, society is less safe due to cell phones.

And, as I pointed out downthread... when's the last time someone actually had to reach you via cell phone for an actual emergency? Particularly when it's something you need to act on rather than just be informed? Virtually all the use of our cell phones falls into "urgent but not important"... the notifications alerting us that Someone Is Wrong On The Internet.
