Steve, you offer the perfect example of what Canute says about personalizing a post by turning what was a note about the ability to charge extra for a certain talent when it is being sought - into a contest about who the better DJ is.
The
fact of actual practice is - that when a performance requires the visual impact of a turntablist - then YES all of your self proclaimed high priced laptop DJs are
not qualified for the job. Those DJs who are qualified may charge a premium for the talent being sought. The methodology you choose to resolve any given job requirement are a factual demonstration of your proficiency. For example. show me a laptop DJ who uses a keyboard and mouse rather than a tactile controller and I'll show you a DJ who lacks the talent to mix. Show me a DJ lacking those kind of talents and I'll show you a DJ who outside of price or convenience offers people
no unique reason to remember him.
BTW: Your opinion about facts is also in fact, just an opinion ..since it is your opinions that formulate your perceptions and therefore the relevant factual outcome of your action or reaction. Thus, while you may challenge someone else's facts with your own - your challenge is formulated only from an opinion and the bias selection of facts to support that opinion, based on an opinion of other facts that fail to support the original opinion. That in fact, is my opinion of the facts. (Say that three times fast!)
That would be an opinion.. where you would find disagreement from all manner of ducks and other water foul.
