Different people, different needs.
On one side, many buy digital pianos or synths with a few dozens adjustable parameters and they are very happy.
On the other side, there are weirdos like me. Before I buy a machine, I read the user manual and most of the time, the ones offering the most possibilities or the largest number of adjustable parameters will be among those I will chose from in the final round before purchase. Of course, I need to connect with the machine playing it live and other criteria, but... That's why I now have a Kronos. And I should continue to discover its possibilities for at least another 5 years. And that is what makes me very happy.
