Some people can't seem to grasp the obvious too. Considering there are THOUSANDS of origianl Korg Trinity's and Triton Classics out there STILL RUNNING on the original touch screens is evidence enough of how well they handle gig use and daily pressing and tapping from fingers.

Taking into account the failure rate for these screens on the current and past models one should be able "grasp the concept" that given Yamaha's lower build quality on their arranger line a touch screen would most likely outlast the buttons themselves... When a Yamaha button fails you can't "always replace just that button".
