Cd drives in computers are more technical than standard stereo players due to their nature of writing to cds. Think higher quality, more accurate equipment.
Edit to add: I remember this was an issue Sony faced, it was selling higher quality dvd players in its PlayStation 2 cheaper than its standalone dvd player series.
It's tricky to define but it has to do with proximity to London (Capital city) and the developing existence of influencers or (it girls) as they were known, combined with poor education and you had a generation of glamorous idiots, that were identified as being from Essex early. Think early Kim Kardashian such as Jordan https://en.wikipedia.org/wiki/Katie_Price
Fine, you are not personally affected by it, but the social disparity that is highlighted by people's need to feel exclusive and yet part of a tribe is the reason.
That's a significant insight. It's only once you've been in a car with someone driving that you really become aware of how "awake"(?) They are. Observance and prediction seem to come with higher intelligence, and some people do not have it.
No, abstract thinking is unnecessary when talking about media.
