Want to piss off your grandma? Tell her that the next time she sets out on a cruise ship she'll be accompanied by the dulcet tones of cell phones. It's the most controversial issue in cruise liner news since plastic glasses hit the ballroom - cell phone enabled cruise ships. Apparently the silver surfers are up-in-arms about the grandkids being able to call them while they're at sea. Just wait until they Titanic - bet they'll be happy about it then.
