The good shops still have at least a few demo units, and if not you can ask someone who works there to bring out a real device to try out. I'm not saying that's a good way to do it but it is at least possible to try them out, if you're determined. For the casual buyer having to ask to try it out is a barrier, and for those just looking it's probably a deterrent.
