Not true. The killer feature for downloads is that you get the content immediately. The difference is that the photography industry didn't deem their loss of control illegal.
That is not a killer feature. It may be a major benefit, but nothing like the step-change that digital cameras were. Think about taking photos at say a wedding, or a fashion shoot, or a birthday party -- how do you know when you've got the perfect shot on a film camera? You don't.
Getting music in 24 minutes or 24 seconds as opposed to 24 hours is not a killer feature. I think another thread hit it with spotify though -- the killer thing will be when you can just play any piece of music on anything and not have to worry about transporting something physical at all. It'll be great, but tricky to price.
