Tactile feedback? I can't think of anything anywhere that has that... you mean raised areas that will change shape depending on function? You are reading too much science fiction...

As to tactile response, the G70 already has it. I know, if I touch a button, it just works. I can feel in my fingers whether I have touched the screen or not. From that point onwards, it's 100% reliable. If I hit it in the right place (hit the wrong button, you still have problems when they are spaced close together, like Variation and fill buttons, etc.) it works. That's all you can ask of ANYTHING.

And yes, it took me longer than a week to get used to it... to the point now that Yamaha's screw me up royally, because I keep hitting the screen to try and make it do something... DOH!
