I think the two have very different symbolism, which is enough to put me off cremation..
I don't really care what happens.. but for those that have to deal with it when I'm gone, I'd prefer to be "laid to rest" than "burned up by flames" which would symbolise something rather hellish in my mind.
That said, I have no problem with cremation, some of my extended family have been cremated.. it's just a personal thing.
