A few people were taken aback that I said the Yamaha build was better.

To tell you the truth I was thinking more in terms of design not build when I wrote that. You're right that the Pa2x is built like a tank. However the Yamaha buttons and screen are way more useful than Korg. A simple glance at the Yamaha keyboard tells you all you need to know, whereas on Korg you have to squint and also check your main screen.

And the Korg screen might be color, but not "full color". The color is completely washed out and doesn't compare with Yamaha which although not exactly a like a laptop screen, is far more vibrant, not to mention double the size.
