For the same reason almost every one else has said, I would not use a "StarTrek" transporter, It kills you, and then creates a copy elsewhere. I would be happy to transfer Physical goods via it, although I would have to think twice about sending something that had a lot of personal meaning. After all it might be a perfect copy, but it is still a copy.
I remember taking a philosophical test on-line some where that asked this question and others, and then tried to tell you what your philosophy was. It said that I was inconsistent for some reason because I was a materialist, yet I would not use the transporter. I disagreed! ;-) I'd love to take the test again, but I cant find it.
Also the stargates used in "Stargate SG1" do effectively the same thing, so I wouldn't use those either. (Just ignore this part when I watch. ;-) )
