I agree with Lawman. You are on a cruise to have fun and relax. There should be plenty to do, see, and enjoy (like the food). Take advantage of it while you can since that is why you spent $x1000 for. If there is a real emergency there are ways to contact the ship and get ahold of you.
I've gone on two crusies. Down to Mexico and around Cuba (Royal Carribean and Princess respectively). I did have my x30 for the Mexico trip and my e755 around Cuba. I used them to write down what I did and display the digital images that I took.
Most cruise ships have an internet center. The internet centers are not attended and require your cabin access card to use, so don't rely on any tech support. During the same cruise, I couldn't find a wireless access point that I could connect to. My sister-in-law used the center during the Mexico trip and she said it was nice....until she saw the charge.
Good luck and enjoy your time away from the World.
