Touch screens rule
The G70 touch screen is a perfect example, shows how a quality touch screen should interface with the OS.

I don't care for the new Korg touch screen...pop ups are annoying, I think the pop up design is for afterthought data..
It becomes as bad as menu driven displays..

For a non touch screen keyboard, the E-A7 with it's dual displays working in conjunction with each other, maintains the flow, making better use than the pop ups on Korg..

I believe all top of the line keyboards should have touch screens..just design them better.
