NEW YORK - The received wisdom that music and video content will be the next killer application for cellphones was belied by a survey conducted among 1,001 cellphone users in February.
    The study conducted by RBC Capital Markets found price to be the single most important factor for most US cellphone users - more so than a built-in camera and music or video facilities.
    Over three-quarters of those interviewed said they aren't interested in watching TV programs or movies on a portable device, and 69% don't envisage listening to music on their cellphones.
