Are you in touch with the asusctl/asusd maintainer/author? They mentioned they got a Zenbook Duo loaner from ASUS and was looking into it, but that was some many weeks ago now.
The asusctl issue tracker is indeed probably a better place to discuss this, so I’ve made a post there.
I’d be curious for your thoughts on the hardware/experience. I’ve heard some conflicting things, especially with respect to the pins on the KB scratching tables when it’s used in dual screen mode.
I’ve only had it for a few days, but here are some very obvious things that I wish all the suspiciously similar reviews would have mentioned:
- The system gets very warm, even in the balanced performance modes. The air blowing out either side can be uncomfortably hot, even when not much is happening - and the lower display gets fairly warm too.
- The hinges have more play to them than I would have liked. The upper display is wobbling slightly as I’m typing this now in laptop mode, and in dual-screen mode at work, the upper display wobbles fairly easily from desk vibrations.
- Due to the heat and hinge letdowns, I’ve taken to using the included sleeve’s stand feature when writing with the pen on the lower screen. Without it, the screen gets hot enough to be uncomfortable, and there’s flex as the display + my hand is supported by the fairly small hinge design. I don’t particularly enjoy writing on inclined surfaces, so this is a bit disappointing.
- As I described in my previous posts, there’s flickering when PSR is enabled. Luckily, both Windows and Linux let you turn this off, though at the cost of power savings.
- As mentioned in the infamous Reddit post, the keyboard is indeed slightly warped in the upper corners, and flexes a little when pressed. In practice, this isn’t an issue, though, as it falls flat within a few minutes of the system powering on. The warping on my unit is only noticeable when in laptop mode, and I’ve had no issues using it on a desk. My wooden desk at home has been fine so far in terms of scratches, but I haven’t used it there all that much.
- The ports are poorly placed. I’d have liked at least one USB port to have been on the right side, and putting the audio jack on the right is pure insanity. I’m not a huge fan of HDMI on the right either, but at least that can be mitigated with a USB-C adapter.
- There are some minor software gripes in Windows:
- The display brightnesses can only be adjusted separately through ScreenXpert, and the only way to open ScreenXpert is through a floating button, which is exactly what you don’t want on an OLED display. Why can’t it be opened through a gesture like the on-screen keyboard!?
- The on-screen keyboard is opened with a six-finger tap, but cannot be dismissed in the same way - the close button must be pressed instead. These control buttons can be glitchy when additional external displays are connected, and sometimes can only be pressed with the mouse cursor.
- The emoji key cannot be remapped. I do not need to send emoji that often. The Bluetooth control key does not send any signal to the OS - I wish it would at least still send F10 when the function lock is on. I had a similar blank function key on my old laptop and enjoyed its constant availability.
- Between the Intel Arc software, the Intel Graphics Command Centre, Windows Settings, and MyASUS, the same display settings are repeated everywhere. Confusingly, they do no always seem to update when changed in another location - so I have no idea if VRR is truly enabled, for example, by looking at any particular settings page.
All that being said, all the positive aspects in the reviews have been accurate, and this device is way better than my previous setup (AU$1,200 4K 2-in-1 with 8th gen Intel + AU$150 external touchscreen monitor). The only thing that hurts is the AU$3,600 price tag 
- I expected better build quality, but this is a first-gen product I suppose.
I hope this helps - let me know if there’s anything else you want to know!
