There is a right tool for the job, and that tool is the one that gets the job done well with the least extra expense for the person doing the job.
But that's the rational engineer viewpoint - and consumers aren't rational engineers. Neither are engineers. If we were, we would all buy the lowest price car that performs the transportation function. There would be no BMW's, Mercedes, or Audi's. There would be only one vehicle in each segment - it would be the least expensive option that gets the job done.
But I'd wager that just about nobody on this site own the car that was the least expensive choice in achieving their transportation needs. Because we don't choose what we need over what we want. We go for what we want almost all the time. That's the whole idea behind branding. People buy a brand because they associate various characteristics and values with a brand, and they feel those characteristics and values match those of themselves, OR (perhaps more importantly) match the characteristics and values they wish they had.
So millions of us run out and buy the new Tiger Woods golf clubs because we want to be Tiger Woods. Or we buy the Lance Armstrong TDF winning cycling outfit replica, because we wish we were like him. Or your wife buys a Chanel or Gucci bag, or you buy anything other than a $3 watch.
The Salae case doesn't cost $50. It probably costs them $5 or less in total to add to their product. But if they dropped it and cut the cost to the bare bones - then they are no different than the Chinese POS supplier. And there is just no way Salae can compete with the Chinese guy selling logic analyzers for $10. They differentiate by going upmarket. But that alone isn't enough - they have to build a brand and make people want to buy into the brand. They do that with a certain look and feel that carries across their brand. That's the reason they have a very schmick (as Dave would say) website, schmick software and schmick hardware. It's all part of the brand that they want people to buy into.
And many, many do - even intelligent engineers. Because we all want to buy beautiful things.
