in reality how many times do you really need service on a keyboard,?
I guess it would depend on how reliable the unit is, plus, it is a new model with the possibility of bugs and other issues. I know that I would want to have good fast service available if I needed it...especially if I was using it to make a living.
Not all keyboard issues are about reliability either...there's always accidental breakage, such as a key or button/slider, or the instrument gets knocked off the stand. It happens.
Have the reassurance of a relatively quick and reasonably accessible repair facility isn't too much to ask for, especially considering the cost of the instrument.
