And let me suggest that all training device, if properly used, have their place -- the square range; IDPA/USPSA competition; classes; force-on-force with simunitions or airsoft; airsoft exercises; etc. -- there are useful things to be learned through all those devices.
The only thing that's not "unreal" is a gunfight, and that has some very significant downsides as a device.
