After the failure of the Chromebook Pixel, it looked like the whole concept of the Chrome OS tablet was dead. Yet with its style, stamina and all-round usability, the IdeaPad Duet turns this around. We can forgive the poor performance in the face of how effectively it manages everything else, and it’s only the lack of size that makes it impractical for more demanding users. If you’re looking for a versatile Chrome OS all-rounder that can handle Android apps, look no further.

For just $249 (64GB), the Lenovo Chromebook Duet is practically a steal. Most Chromebooks in the sub-$300 space are clunky 14-inchers that offer little in the way of flexibility. The Duet is more flexible and more affordable than much of the competition, and that makes it a powerful foe. It’s not perfect. The keyboard may simply be too small for some, and performance can be hit or miss, depending on what you’re doing. It’s not entirely stable on your lap, though it works well on a table or desk. And some may simply not be down with Chrome OS as a tablet user interface. I think these weaknesses are worth overlooking. On the plus side, the Duet offers a fine display, class-leading battery life, and a compact and portable form factor that converts from laptop to tablet on a whim. Most importantly, it’s affordable. Even the $299 (128GB) version is priced competitively. It costs less than an entry-level iPad — and the keyboard is included.

The Lenovo Chromebook Duet 3 is a fantastic value at $300, particularly given that the folio kickstand and detachable keyboard are included. And it’s not just about the price — this little Chrome OS tablet can handle a surprising range of tasks, falling short of only the most demanding productivity and creative workflows. You’ll spend hundreds of dollars more for a similar setup that won’t gain you much additional functionality. The Lenovo Chromebook Duet 3 is the best budget Chrome OS tablet (a little) money can buy.

Lenovo brands the Lenovo Duet as a device that can do it all: it can work hard when you need it but gets out of the way when you just want to play games or watch movies. In my experience, I'm not sure how many of us would want to use a 10.1-inch screen as our primary computer, but the Duet can hack it for my work — answering emails, research, writing, and photo editing — and I bet it can hack it for yours, too. Where the Duet really shines is as a companion device, as a tablet that you can use while the kids are hogging the family computer or you're in the backyard away from your desktop. The Duet is a battery-sipping beauty that may not be the sleekest or shiniest tablet around, but it's certainly the most practical tablet out there. Even as we head into 2022, that's exactly what we need. Chrome OS offers you a desktop-grade experience when you need to VPN into work for a quick report or knock out a few dozen emails while you wait for everyone to assemble for movie night, and it offers up battery life that stands out even among Chromebooks.

The Lenovo IdeaPad Duet Chromebook strikes the perfect balance between tablet portability and Chromebook utility, all while keeping the price ridiculously low - and somehow packing in a Lich King of a battery that simply refuses to die. Finally, it does all this for less than $300. As far as Chromebooks and 2-in-1 laptops go, this is the best value you're going to find in a portable device of its kind, hands down. It's the computer that last decade's netbooks promised to be - but couldn't quite become - while taking the Chromebook to its next logical step.

I really enjoyed my time with the Duet. It scratches that itch of quick productivity, but it also delivers a good second screen experience when sitting on the couch or when my daughter wants to watch something while we're out at dinner. It generally lives either in my work bag, where I do not even notice its presence, or in the kitchen where I use it almost every time I walk in to make some food. I'm never going to try and game on this thing nor do I expect to do heavy video editing. That's just not what it's designed to do. At less than $300, I don't think you're going to find much better than this on the market in the next year or so.

This Lenovo Chromebook Duet review shows why it should garner deserved attention for its value proposition, giving you a 2-in-1 with a solid screen and long endurance for less than the iPad or Surface Go 2 cost, before their keyboards. If only its keyboard weren't so cramped and its hinge felt a bit more solid. Those who opt for the Surface Go 2 for its faster performance and superior 2-in-1 design, you'll be dropping about an hour of battery life and paying at least $221 more after throwing in the Type Cover keyboard. But for families looking for a device that everyone can use, from kids watching YouTube to parents drafting emails, the Lenovo Chromebook Duet is a compelling option.

Google might have given up on the idea of a Chrome OS tablet with the demise of the Pixel Slate, but that hasn’t stopped Lenovo. The IdeaPad Duet is a 10.1in tablet running Chrome OS and supplied with a rear cover that doubles as a fold-out stand, plus a magnetic clip-on keyboard that instantly transforms it into a productivity device. Take a look at the price and you’ll expect the result to be a disaster, but here’s the surprise: while far from perfect, the IdeaPad Duet turns out to be a little wonder.

There’s a lot to like with the Lenovo Duet Chromebook: it is well-priced, has a good screen and works well as a tablet. It is less successful as a laptop, though: the keyboard and touchpad are too small to be comfortable to use for longer periods. If you are typing all day long, get a dedicated Chromebook with a bigger keyboard.

So long as you know the limitations going in, the Duet is a very likeable device that offers strong value for money. Make no mistake, this is no powerhouse and the cramped keyboard won’t be for everyone, but when it comes to general computing and shorter-length writing duties it’s a lovely little 2-in-1 Chromebook that can double as a serviceable Android tablet.

Chrome keeps growing in features and this two-in-one will continue to get updates every six weeks for the next eight years. As your main device, its performance and size may be a little limiting. But if you're looking for something for pure mobility or as a secondary device, this is a smart choice. I can certainly see why Chrome users are excited about it, especially at $300 or less.

When announced at CES this year, the Lenovo Duet Chromebook attracted a lot of attention for putting some great features and looks into a budget-priced ChromeOS tablet. Everyone was intrigued – would it live up to the hype? Travis and I each bought one once they were released, and are ready to share some impressions after a few months of use.

When it boils down to the basics, the Lenovo Duet is an impressive machine. Generally, when computers get down to this price, there are some major trade-offs, but for the most part, Lenovo has been able to make the right calls when constructing the Duet.

The Lenovo Chromebook Duet is an astonishingly good value device, coming bundled with a detachable keyboard in order to undercut the price of the iPad and Surface Go 2 by a couple hundred quid.

I would recommend the Duet as a buy for anyone who wants to cautiously move to ChromeOS, a secondary device, an in-a-pinch substitute or a an additional screen in this new work-from-home reality. I don’t think the current Duet is ready to take on heavy workloads just yet, but if Lenovo keeps at it, the Duet 2 might be in the conversation with iPad Pro, Galaxy Tabs, and Surface Pros with just a few tweaks. Will ChromeOS keep pace? That may be another story.

As someone who has made use of a Surface Go for a long time (I used it at MWC last year even) I love the smaller, more portable form factor. I don’t mind a smaller keyboard — I’m not a full touch-typer anyway so it did not fuss me too much. I would have liked the keyboard to be backlit though but that of course depends on where and when you use it yourself.

There's a lot of good with the Lenovo Chromebook Duet, and when you consider the price, it's pretty much all good. This device looks and feels premium with its aluminum build, two-tone design, and excellent display. And I want to once again point out that the keyboard and kickstand both come in the box for that low price of $279, which is lower than the price of just Apple's Magic Keyboard.

The Lenovo Chromebook Duet is a surprising success. For less than $300, you get a capable tablet with good battery life, performance that’s adequate for basic use and an attachable keyboard. It’s tiny, so not the kind of device you’ll want to use all day every day. But as an inexpensive Chrome OS device, it checks most of the boxes.

If you’re looking for a fun device for kids that can also handle homeschooling work, or a portable 2-in-1 for watching Netflix and sending emails on the go, the Duet should do just fine. It’s a solid midrange 2-in-1 Chromebook that has no business being as cheap as it is.

The Chromebook Duet earns an honorable mention among Chromebooks for consumers and captures our Editors' Choice among Chromebooks for students. Besides being a bargain, it's a thoughtfully designed and well-crafted detachable, especially for Android phone owners; the tablet and its peripherals have the look and feel of a product costing much more. As you use it, you keep discovering things—from the cameras to the screen brightness—that are better than you expected. I wish it had a faster CPU, but I believe a lot of users will be very happy with it.

The Lenovo Chromebook Duet is a surprisingly affordable 2-in-1 looking to find a path for a troubled kind of Chromebook. Chromebook fans might remember the Pixel Slate, which didn't thrive and was followed by reports that Google wasn't making first-party ChromeOS tablets anymore. Now, thanks to a partnership with Lenovo, a fantastically low price and tablet-based optimizations, it just might work.

Overall, Lenovo has absolutely delivered a stellar tablet/laptop experience with the Chromebook Duet. Sure, I’d like to see a fingerprint scanner included and I’m excited about tablets like this in the future with even better ARM chips than this, but this all just proves that ‘Kukui’ (the baseboard this device is built upon) tablets are going to be what breathe life back into the idea of a Chrome OS tablets again. Lenovo expects to begin shipping the Chromebook Duet by May, so we won’t have too long to wait for the official release of the first of many new Chrome OS tablets.

We’ll answer that question in May when the Duet comes to market, and we’ve had a chance to review it, but based on my first impressions, I’m pretty confident that this will be an easy product to recommend, considering its $279 price tag. Our own Kyle Bradshaw also seems quite excited at the prospect of this being a Stadia machine…
