i'm still undecided on mp3. it is quick and convenient for ableton, but I hate the fact that it isn't a physical product to hold and smell. Nothing to sell on either should you decide that its the end of the road. I'll be buying both for the forseeable future. And as my mate owns a record shop which he runs as a hobby, as he's an architect by trade, then I can see it being a fairly lengthy forseeable future
