"Underwhelmed" sounds like my feelings about Pa5X so far as well. I often have an impulse to sell all the gear I have and to stick to a decent guitar and a decent piano (digital). But when I play my PSR as a piano, I start to add strings, controlled with a pedal, or chimes, using multi pads - things not possible on digital pianos...Then I want to play with styles "just for a moment, just to try it"... Then I want to play an electric guitar voice, which works only with styles.... Eventually, it tells me that I still need an arranger. Considering unpredictability of our world, hoarding doesn't seem like an unreasonable behavior. As for digital pianos, I'm tempted with stage pianos, like Yamaha CP73/88. It's closer to a traditional instrument than an arranger or workstation, but there's still a possibility to modify it, try different sounds, in other words, not only to play it, but also to play with it. But there are no speakers inside, eventually it happens to be a big deal.
