My grandmother is against cremation, and had my grandfather buried. (We had hoped she would allow cremation, so we could lay him to rest at a military cemetery in San Diego right next to the ocean; but we had to settle for burying him in Riverside, far away.) Money can be an issue too, so I think it all just depends on what is financially viable.
Personally, I'm all for cremation. In fact, I'd like to have a Darth Vader-style funeral pyre... Otherwise, I'd be good with a Viking style funeral, with my body, all my belongings, and my wife sent off in a flaming boat, (she can jump off once the boat starts to sink, heh heh).
