This was worth the wait!
The 2025 version of this laptop comes with the Ultra 9 285H CPU, which was worth the wait. There are a ton of YouTube video reviews, so I will not go into all of the details - you should definitely watch them first, but here are my pros and cons:Pros:You can use it like a regular laptop, and it is totally stable and the keyboard is *great*.The OLED screens are beautiful and bright (though reflective in bright light).The vertical mode is super stable and easy to get used to.Moving apps between screens is simple, and I have had no problems at all.In "standard" mode, I almost never hear the fans, even with multiple programs running.The system uses a small 65W power brick...any 65W or higher PD brick will be fine.The premium body is not a fingerprint magnet.Battery life seems good, but I have not used it too much without ACComes with the active pen, but I have no use for itThe MyAsus application is very good, and puts the system controls in one placeCons:Heavier than your usual 14" laptop, but you have 2 screens :-)Two Thunderbolt 4 ports - why not TB 5?The keyboard battery life when removed from the body seems a bit short when the backlight is onThe CPU can take more power, but it is limited in this machine to prevent it from throttling too muchBattery life is limited due to the two screens, but that is to be expectedWhy not Win 11 Professional instead of Home for a premium device?There is only 1 M.2 slot for storage, which is a bummerOverall, this is one of the best machines I have ever used. Applications are quick, and I am never waiting for something to respond. This is NOT a gaming machine, regardless of what you might hear. The iGPU is not the best that Intel has to offer, and the NPU for AI is weaker than most - but for what it is meant to do, it excels. This is a business laptop dream - if you multi-task a lot, edit multiple documents at once, etc., it is perfect. Did I mention how great the keyboard is? :-)Highly recommended!R

Best Productivity Tool
The ASUS Zenbook Duo UX8406 is not just a laptop; it’s a game-changer that redefines what portable computing can be. With its innovative dual 14-inch 3K OLED touchscreens, powerful Intel Core Ultra processors, and a sleek, versatile design, this laptop is a dream for multitaskers, creators, and professionals alike. Intel Core Ultra 9 285H processor with an AI Boost NPU, 32GB of LPDDR5x RAM, and a 1TB PCIe 4.0 SSD, handled everything I threw at it—from video editing to light gaming—without breaking a sweat. The Intel Arc graphics provide a surprising punch for creative tasks, though this isn’t a gaming rig. The laptop’s AI capabilities shine in tasks like real-time video effects and optimized power management, making it a forward-thinking choice for the AI-driven future.Pros:Dual 14-inch 3K OLED touchscreens are gorgeous and versatilePowerful Intel Core Ultra 9 with AI capabilitiesImpressive battery life for a dual-screen deviceDetachable keyboard and stylus enhance flexibilitySturdy build with a clever kickstandCons:Speakers lack depthSlightly heavier than single-screen ultraportables (but worth every extra for the productivity!)Reflective screens can be tricky in bright light (I use Matte screen protectors and this is a great addition)This is my everyday laptop for work and for home. I have a separate gaming pc with an RTX GPU. That said, this can run GTA V Enhanced no problem and even Stalker 2 at low settings. This by far is Asus's best creation so far for productivity yet.

Zenbook DUO is a travel winner!
The Zenbook Duo 2025 model has been great to use. I travel for work and have often carried a second monitor to work on Outlook, Excel files and PowerPoints. Having this setup streamlines the workflow and makes setting up the laptop so much quicker than plugging in another monitor to HDMI and power. When on the airplane, I use it as a regular laptop and the 14" size is perfect, just slightly bigger than 13" and fits in the workspace. The detachable keyboard is also a huge benefit so you can slide the screens forward and work comfortably. Speed has been great on the unit, I'm coming from a Dell XPS13 that is 3 years old and I find the Asus build quality on par with that brand. Great price also compared to the Dell model. I have the faster processor and noise has been low when the fan is on. I highly recommend this model.

Perfect product!
I bought an ASUS laptop and so far it has exceeded my expectations. From the first use you can tell it is well built: it is light, thin and with an elegant design, but at the same time resistant. The performance is excellent: it boots up fast, handles multiple tasks without a problem and runs heavy programs without bogging down, thanks to the processor and the good amount of RAM. The screen has a crisp image quality, ideal for both working and watching multimedia content. The battery life also surprised me: it lasts several hours with moderate use. Another strong point is the cooling system, which prevents it from getting very hot even with prolonged use. All in all, ASUS has left a very good impression on me for its value for money, performance and durability. Recommended.
