I agree that the Touch screen is not really a cost issue...but I'm sure you'll agree, as it has already been mentioned by Gary, that replacing a button or two, would be far cheaper than replacing a defective touch screen.

Sure, whilst under warranty, it would not be an issue to the user, but it would certainly be a great benefit to a long term user or a second hand buyer.

Yamaha has wisely kept to the buttons, making their already superior OS and user interface (in my opinion) even more enticing.
