Cell phone industry = Tobacco industry of the 21st century

We just moved offices at Judy's Book. We've been using cell phones while we try to figure out exactly what to do for an office phone : voip vs. Qwest!?

My partner and I have been using cell phones more and we've concluded that there is nothing good from using cell phones (with or without the ear piece). I personally am convinced that having a microwave in my ear for 4 hours a day is likely to lead to no good. What do you think ?

Do you have any good research sources on this topic?
