The trouble with the no-computer description is that, for at least twenty years now, computers HAVE been central to making music, to the point that there is a whole generation of mature musicians that feel more comfortable on a computer making a music production, than 'within the box' of a self-contained WS.

Sadly, I only really see either older players or complete technophobes trying for the 'in the box' experience any more. To the point where one of the most popular new additions to WS features is the ability to control external computer DAW's and VSTi's from the keyboard itself. Hardly the sign of a generation looking to rid themselves of the DAW...

Although you CAN put together a pretty decent production withing a WS entirely by itself, I see VERY few players doing that any more...
