I had a PA900 before and I sold it. I found it not too practical to adjust the screen-based sliders or knobs in real-time situations. Hopefully they made substantial improvements on the screen tactile response as you said. I'll eagerly wait for your review when you got your PA1000.
Thanks Uncle Dave
