I have an earlier DUO model, one with the half-screen between the main and the keyboard. While shopping for a replacement for a laptop that had been dropped a few too many times, manic me bought it as a gimmick and when it arrived I feared it would just be that. I have found it genuinely useful in various ways though: during dev with various small utility tabs on the lower screen, messaging on bottom screen with full-screen video on top, smaller video and/or messaging on bottom with work on top, etc. Handy that you can easily turn it almost off too, to save battery when mobile.
I still carry a 14" external (USB3) monitor for when at a desk. The extra half-screen is still useful in those circumstances, though, just not as much so.
To make Windows11's taskbar less irritating (which it is even more so, if you can imagine that, with an extra screen under your primary) I recommend using something like ExporerPatcher or another shell improver/replacement.
I have the Zyphreus Duo ( https://rog.asus.com/in/laptops/rog-zephyrus/rog-zephyrus-du... ) with the touch screen in between the screen and the keyboard. Its perfect for todo/whatsapp/zoom/file explorer and I have an external screen/keyboard/mouse (so in total 2.5 screens). Perfect desktop replacement and a good gaming laptop. Mobility is limited due to battery life but it suits my needs.
Mine is from the much lower-spec (and appropriately cheaper) ZenBook DUO range. The battery life is pretty darn good until I plug in the external screen, and still better than many laptops even then. It isn't often I'm away from a power socket for and needing to work, but when I am, it can be for a fair few hours. Gaming isn't something I find time for these days, so this model is much better value for this use pattern.
Yes, your model makes sense if you dont require gaming. Asus really makes the best devices. I have been theirs's and HTC fan for years. Had Lamborghini laptop from Asus and HTC diamond phone circa 2008-9.
