It's a shame really...
You asked a very intelligent question about a very straightforward marketing matter called 'lifestyle positioning' - it's all to do with demographic profiling; but I don't think any of the major producers of keyboards employ or take notice of anyone with that knowledge or those skills.
Very simply either by intent or by chance public awareness of your company and its products will 'position' itself in their minds as being useful for one type of thing or another and therefore appropriate to one type of individual or another - if you know what you are doing from a marketing standpoint you deliberately set out, by dint of your public activities to create particular 'image dimensions' for your company or product.
One may ask as an example - what are Technics deliberately setting out to do so that the public perceives their newest product the KN2600 to be targeting a younger audience?
