The Department of Transportation is considering a ban on the use of cellphones for voice calls aboard airplanes. While this news may come as music some business owners' ears, others might disagree.

In recent weeks, the Federal Communication Commission moved to lift the rules constraining in-flight cellphone use--opening the door to being able to not only check email and send text messages, but also make voice calls.

Naturally, not everyone is thrilled about the change. Forty-eight percent of Americans in a recent Associated Press-GfK poll want to prevent the use of voice calls from cellphones on flights. Nineteen percent of those surveyed are happy with the change, while 30 percent are noncommittal.

Still, there's surely a business case for being able to make in-flight calls without drawing the ire of flight attendants and passengers. What if you need to make a quick call to a vendor or key customer, and it can't wait? Should there really be a ban against a perfectly safe use of technology?
