It looks like everything is working as expected to me when I modified the PG to the following:

"However, the onTouchpadButtonStateChangedObservable is still returning zero for the value btw. Is this actually expected ?"
I believe so. I think the value field maps to the pressed boolean on the button state and will be set to 1 when the trackpad is clicked. There is another boolean on the the state called touched which can be used to check for when it gets touched.
