Functional and versatile
I have had this laptop for 5 months and I absolutely love it. I wasn't convinced at first but now I don't think I could work with out it. I need a double screen for work which meant working in my office all the time. Now I can work off my lap desk on the couch. It came in really handy when I broke my ankle and had to be on the couch elevating and icing for 8 weeks. My work didn't slow down because I had 2 screens! It is very sturdy when using the second screen, the stand is tight. It does get a lot hotter than my last asus with one screen but it is minor issue. The battery life is shorter than other laptops especially when using duel screens. It lasts about 2 hours. The Bluetooth keyboard is fantastic and lasts on batter for several hours. The sound is also good as I am on video calls much of my day and it is always crystal clear. I was hesitant with new technology but I would definitely buy this again in a heartbeat.

Dual Screen Powerhouse! Best Investment I've Made
If you work from home or frequently travel for work and rely on multiple screens to stay productive, the Asus Zenbook Duo is a game-changer. I’m genuinely thrilled with my purchase. The dual touchscreen displays are not just a gimmick—they’re a thoughtful and practical innovation that makes multitasking significantly more efficient. The main display is vibrant and crisp, perfect for editing documents, video conferencing, or streaming. But it’s the ScreenPad Plus, the second display, that truly sets this laptop apart. It allows me to keep communication apps, reference documents, or tools like Photoshop layers or video timelines open and accessible without cluttering my primary workspace. It feels like having a dual-monitor setup packed into a portable form factor. The touchscreens are responsive and intuitive, and the stylus support adds another layer of productivity, especially for creative professionals or anyone who takes notes or sketches. The build quality is excellent—solid, sleek, and surprisingly lightweight given the tech it packs. Performance-wise, the Zenbook Duo handles my workflow smoothly, from video editing to running multiple virtual desktops. The keyboard placement takes a little getting used to due to the shifted layout (because of the second screen), but it becomes comfortable quickly, especially with the included palm rest. Battery life is respectable considering the power demands of dual displays, and the fan noise is minimal under most loads. In short, if you're a multitasker, creative, or remote worker who thrives with multiple screens, the Asus Zenbook Duo is one of the best investments you can make. It redefines what a laptop can do.

Many great things but a fatal flaw with keyboard typing double characters
This laptop has an interesting design. I've had it for a week now and quite enjoy some aspects of it. However, it has a fatal flaw that is going to lead me to return it if ASUS cannot fix it (which seems doubtful). The keyboard has a chatter problem. Frequently, it will insert double characters from keyboard bounce when typing. Most noticeable is that it will change "the" to thee". I thought my poor typing was just due to adjusting to a new keyboard, but after a while I realized that it was the computer. You can learn more if you search for "thee" "ASUS" and "chatter." You will find others having this issue for ASUS machines, not even just this model. Notably, a plug-in keyboard works just fine. I have now spent hours dealing with ASUS support and trying to figure out what is going on. ASUS is given me a bit of a runaround, saying I need to send the entire unit back for repair, which will waste a lot of my time. I am likely to simply return the unit because other people have done such an exchange and the new unit has the exact same issue. I have asked them to send me a new keyboard to try but as of yet they are unwilling to do that. I will not fix thee typos in this paragraph. I ended up buying a second computer. It has the exact same problem, straight out of the box. I have attached a video showing thee chatter on thee key 'e' (it is making mistakes right now). 'e' is not thee only key that has a problem, but it may be thee most noticeable, as you can see from the paragraph where I have not corrected the problem. It's really a shame, because the dual-screen design is a terrific productivity enhancer, the pen seems good, etc. I've noticed some other little quirky things with the unit when running off the battery, but it is this keyboard issue that is a fatal flaw. By running a piece of special software to detect and help reduce the problem (Keyboard Chatter Blocker), I am able to do things like write this review without typos everywhere. When I turn it off (last paragraph), it's a disaster. Unfortunately, while that program helps tremendously, it is impossible to tune it perfectly. Typing will be disrupted no matter what on this machine. If you care about what you type being accurate and not having a maddening problem every time you type, buyer beware. Search online and you will see other people mention the "thee" problem.

Most impressive
I am a daily MacBook Pro user. Here is my biased assessment. PROS: I am impressed with this laptop. It is very well built. The dual 3K screens are very bright. The GeekBench 6 score is 12,700 which beats my M1 MacBook Pro. It feels very fast. The keyboard is very light and works well. I can connect this laptop to my dual LG Ultrafine displays using the dual Thunderbolt ports. It will power one of the Ultrafine displays at 5K but will power them both if the resolution is set to 4K. So I get 4 screens connected in this configuration. The screen navigator detects all 4 screens and allows apps to be sent to any display easily. CONS: A few times I've had to restart the laptop to get it to recognize both LG displays. I don't know how long the battery on the keyboard/trackpad will last. It appears to only run a 4 or 5 hours on a full battery but it accepts USB-C power. I recommend this laptop. It is my favorite piece of hardware. Using dual 3K screens is a game changer. It makes this laptop a pleasure to use.

A few hiccups but overall GREATEST LAPTOP EVER MADE
After a few months working with this amazing piece of hardware, there are a few minor glitches here and there but overall this is an incredible work horse that massively ups your productivity. I'm someone that has carried around a 2nd screen for years finding productivity increases significantly with a second screen. Now, being able to easily set up a 2-display scenario and code is just a dream come true. This machine makes me want to code, makes me want to work. Or if I'm in off work mode and just want to read reddit in one screen and watch football in the other, that's perfect too. There are a few minor hickups here and there but overall worlds better than any macbook or surface on the market, this is THE machine. --- previous review below --- Haven't found anything really to dislike yet (other than Windows 11 lol, 10 is superior). Was wondering how the build quality would be on the first go of a design like this, and so far it seems good. Stand is sturdy, I can prop it up even on my bed. In laptop mode (one screen) it's a little thicker than the single-screen Zenbooks from the last few years. Screens are pretty and very vibrant. Overall another great product from Asus. Why anyone would buy a Lenovo or HP I will never understand. edit: Install "Explorer patcher" for windows 11 to get the superior windows 10 start menu. Rear hinge is fantastic, much stronger and wider than expected. Dual screen mode will even prop up on a bed. Pleasantly surprised.

Good laptop, I like it, has some flaws.
The screen is very nice, build quality is great, feels like a premium device. My biggest problems is the detaching keyboard process isnt very seemless, I felt like there was more they could have done with the software to make it smoother, I had to go into advanced windows settings and remove the windows usb connect sound as it was so irritating while taking off the keyboard. Another huge problem is heat and battery life, with basic web browsing it gets insanely hot and the battery drains very quickly!!! Asus advertised 10 hours on one screen which is entirely unrealistic. The performance is worse than I expected for a new gen intel cpu, I dont think they've gotten better. Some smaller issues is the trackpad is very grippy, I'm not an artist but the included pen seems terrible, each time i slighly touch the palm of my hand to the screen while using, it completely messes up. IMO they should have lowered the price to 999 and not included the pen and bag!!

Vastly exceeds expectations in performance and coolness. The price point is exceptional as well.
This was a "I need to treat myself" purchase. I've been a programmer since the 70s and the "cool" factor of this style of laptop just won over good sense (so I thought.) I've got the i9, 32g version. It's slicker'n whale...err..."leavings." I sent pictures of it with the keyboard detached to friends and when I finally hung out with them they asked why I didn't bring the 2nd monitor. The wide-eyed "oh my god!" ness when I showed them was worth it. Fun stuff aside, it's really well made. It's not too small to code on (I type really fast.) And, if you don't want to use it in one of it's "funky" configurations then it just looks and feels for all the world like a normal laptop. Performance is impressive. But given the specs, that's almost not worth bothering to say. Admittedly I haven't run taxing benchmarks on it or anything. Just a bunch of processing, coding, database servers and number crunching. A word about the video resolution: It's good enough that I have to have the desktop environment scaled to 200% to be able to see it. And no, that's not just because I'm old ;-) Battery life, even with both screens active, is a clean 5-6 hours active working time which is more than enough for my use. I put Ubuntu Linux on it right out of the gate and was worried about the pen/touchscreen interface support. But it's a non issue. The only thing that would take this from 10/10 to 15/10 is if the screen folded "all the way around" so I could use it like a tablet. But that's REALLY nitpicky. This is a straight up win and will be not only my daily driver, but dev machine for the forseable future. "Can't wait to see what they think of next." - Old guy.

Dual Monitor Laptops are the Future of Productivity!
I had seriously considered the Lenovo Yoga Book 9i last year as I've long wanted a dual monitor laptop. However, I could never pull the trigger, partially due to the cost, but mainly because the "stand" and keyboard solution Lenovo came up with seemed to be just as cumbersome to travel with as a second monitor would be. What I had really wanted was a dual monitor laptop with the keyboard stowed in-between the screen like Lenovo did with their X1 foldable, and with a built-in kickstand. Just waiting one more year after the Yoga Book 9i came out allowed me to purchase this ASUS Zenbook Duo 2024. My model is the "lower" end Core i7 with 16GB RAM and 1080p monitors. For my purposes, the i7 and 16GB RAM are plenty, as is the 1080p resolution. I'm not even sure why the higher end model has such high resolution displays, as the screens are only 14" so 1080p is plenty for me, while 3K displays on such a small footprint means more battery drain pushing all those additional pixels. The additional cost is worth it if you need the RAM and higher speed processor, though I'd still lower the resolution to 1080p had I purchased that model. Regarding build quality, I did not buy in the first production run, (which didn't even include this model as far as I can tell) and I have zero complaints. No creaking, ill-fitting, or unproperly spaced components. It feels extremely solid and well made. If there were early production-run QA issues it seems that they've been addressed by ASUS at this point. The laptop is on the heavier side, but for what it includes it is well worth it, and still significantly lighter than carrying a laptop along with a second monitor. Upon receiving and booting up the laptop there were definitely some software quirks related to the displays, (they wouldn't properly rotate when the physical orientation changed). However, I went in to Windows Update and had it download all new updates, which also came with new ASUS drivers and that fixed the rotation related issues I was having while also making the system run much more smoothly. Obviously the system was manufactured some time ago while software development has continued, (and still continues). I had expected some Windows-related issues as this is a new form factor, but other than the first rotation bug, it's been pretty seamless and you can just use the second display exactly like you would any other second display - it is just built in! The keyboard solution is great, as is the keyboard itself. No compromises here and all keys register quickly and easily, whether docked or on Bluetooth. I'm quite happy with the keyboard and trackpad, and when using it in regular laptop mode, (with just the top display) you'll easily forget that there's a second display underneath. Opening up the laptop and propping it up with the built-in kickstand is a game changer. Everything you need, (with the exception of an external mouse) is built right into the machine. You can carry it all with you in a compact and relatively lightweight package. If you are the kind of person whose work benefits significantly by having a second display, this is a form factor you should highly consider. I am also quite pleased with the quality of the displays themselves. They get plenty bright for outdoor use, (I used them outside for a week on a recent trip to Grenada) and "pop" with bright colors while being easy to read in just about any environment. These seem to be quite high quality panels, which I would expect given the price, but you never know. I can't really comment much on system performance as all of my work is browser based, but I can say that it is extremely snappy with dozens of open tabs and at least four applications running side by side across the two open displays. If you're running Photoshop, editing CAD drawings, or other CPU/RAM intensive programs I'd probably just opt for the higher-end model as it is only a few hundred dollars more. Still, for my use, this model has been fantastic and a significant performance upgrade over my previous 2021 laptop. Overall I am extremely happy with this purchase. The ability to have a second display is crucial for my business, and working without one adds a significant amount of time to any task I need to complete. In many cases my work is very time sensitive, and I value my time highly, so this is the perfect solution. I am excited to see how ASUS continues to innovate on this idea.
