Asus Transformer Book Duet officially announced, Android to Windows in less than eight seconds

by: Andrew GrushJanuary 6, 2014


Just yesterday we reported that Asus had leaked news of the Transformer Book Duet through an accidentally (maybe?) released video, which it ended up taking down. Now at their press conference, Asus has made it official!

The new Transformer Book Duet is what Asus is calling a “4-in-1 laptop and tablet” that runs both Windows and Android. Unlike most devices that have attempted to throw both OSes onto the same hardware, Asus says their implementation isn’t running Android on top of Windows or vice versa.

Does that mean you’ll have to shut down and reboot to change your operating system? Nope, thanks to Asus Instant Switch technology it only takes a matter of seconds to switch from Windows to Android and back.

Asus Transformer Book Duet Specifications

  • Dual-OS – Windows 8.1 Standard / Android 4.2.2
  • 13.3-inch Full HD IPS multi-touch display
  • Up to Intel Core i7 processor
  • 4GB DDR3L 1600 RAM
  • Up to 128GB SSD in Tablet
  • Up to 1TB HDD in Dock
  • 38WHr battery, estimated battery life around 5 hours in Windows 8.1 and 6 hours in Android 4.2.2.
  • 802.11ac Wi-Fi; Bluetooth 4.0 + EDR
  • Tablet ports: Micro SD card, Headphone jack, DC jack
  • Keyboard dock ports: 1 x USB 3.0, 2 x USB 2.0, 10/100Mbit/s LAN, HDMI 1.4, audio combo jack, DC jack

As you can see, the Duet packages a pretty mean punch, though on the downside it’s also a bit heavier than a typical ultrabook or tablet. When using as a laptop, the total weight is around 4.1 pounds. Even the tablet itself is a bit thicker, though it’s probably worth the sacrifice if you’re looking for one device to rule them all.

Pricing and Availability

There’s no specific release date just yet, but Asus did reveal that pricing will begin at just $599. It’s unclear what processor or storage configuration you get for that price tag, however.

The Asus Transformer Book Duet certainly isn’t for everyone, but it could still be a solid device for those Android fans that occasionally have need of Windows for gaming, business and other uses — at least if it can provide the seamless Android/Windows experience that Asus claims it can.

What do you think of the Asus Tranformer Book Duet, impressed or not? We’ll be sure to get our hands on this one soon, so be sure to stay tuned to Android Authority!

Show Press Release
Las Vegas, NV (January 6, 2014) — ASUS today announced Transformer Book Duet (TD300), the world’s first quad-mode, dual-OS laptop and tablet convertible that allows users to switch between Windows and Android in either laptop or tablet modes with just a single push of the Instant Switch button or a virtual key on the tablet. With a powerful Intel® Core™ i7 processor at its heart, Transformer Book Duet runs up to twice as fast as existing tablets based on ARM® processors. ASUS SonicMaster technology and dual speakers ensure that Transformer Book Duet delivers incredible audio for immersive entertainment.

Quad-mode, dual-OS laptop and tablet with Instant Switch

ASUS Transformer Book Duet (TD300) is an extremely capable device that is able to function as an Android or Windows 8.1 tablet or notebook. Users can simply switch operating systems with a single push of the Instant Switch button or a virtual key on the tablet.

By offering both operating systems, ASUS provides users the ability to run supported Android applications and a vast array of native Windows applications. Transformer Book Duet features a powerful Intel Core i7 processor with Intel HD graphics and 4G DDR3L 1600 RAM, giving it performance that’s up to twice as fast as existing tablets powered by ARM® processors.

The patented ASUS technology that powers Instant Switch offers many performance and productivity benefits over other dual-OS solutions, such as fast, smooth and seamless switching and the ability to resume each OS from where the user left off. As it does not use OS virtualization, Instant Switch also allows each OS to harness the full power of Intel’s latest processor technology.

Striking audio-visuals

ASUS Transformer Book Duet (TD300) delivers striking visuals on its 13.3-inch 1920 x 1080 Full HD IPS touchscreen display. This multi-touch display features sensitivity and responsiveness that exceeds Microsoft’s requirements for Windows 8.1. For audio, it comes with ASUS SonicMaster technology for true-to-life sound through the tablet’s dual speakers.

In addition, Transformer Book Duet has a front-facing HD camera with a built-in digital mic for video chats. The tablet display has 128GB of SSD storage that can be supplemented by a 64GB Micro SD card, while the keyboard dock houses up to a 1TB hard disk drive. The dock is also home to USB 3.0 and USB 2.0 ports, a LAN port, and HDMI 1.4 output with 1080p support. In terms of connectivity, ASUS Transformer Book T300 has 802.11ac Wi-Fi and Bluetooth 4.0 with EDR.

ASUS Transformer Book Duet sports the same stylish concentric-circle finish found in other ASUS offerings. The Transformer Book Duet has compact dimensions, with the tablet measuring 342.7 x 216.3 x 12.9mm; and the dock measuring 340.9 x 217.6 x 16mm. Together, they weigh around 1.9kg, making it supremely portable and flexible for those on the go.

    Holy balls Batman! Though the device wasn’t a surprise, the possible specs and starting price are pretty amazing! Also that tablet part looks really thin, like 6mm o.O

    • elysium

      5 hours battery life in Windows 8.1 and 6 hours in Android 4.2.2 is far from amazing. Even older Asus Book T100 can get 11 hours with Win 8.1 .

      Seriously are both OS run in parallel ? If that’s the case, no surprise with battery life..

  • Ryu

    Depending on the starting price, it could be awesome. If there is no wacom pen support I won’t get it, though.

    • Memphis May [S]unjay

      Starting at $599.

      • Ryu

        My bad, I meant to say “starting price specifications”

        • Memphis May [S]unjay

          Aha, I see :)

    • Tom Seleck’s Ulcer

      I’ll get you a BIC pen at Staples…now piss off

      • Ryu

        I only use fountain pens for RL writing, not shitty ballpoint pens, asshole.

        I need a wacom digitizer for digital art.

  • shit

    The $600 is going to bring the most bullshit specs with it. I can see it now: 64GB (and remember that that needs to be allotted for two OSes on one device), and somewhere near 128GB – 256GB on dock, and an Intel Core i3 just to fuck with you.

    • Memphis May [S]unjay

      Starting at $600, it’s a way better deal than an iPad.

  • Shark Bait

    Android just doesn’t work as a deskptop for me. Did any one see the verge piece on the webOS desktop interface that never made it out of HP? I think it looked pretty good, amd very unique. I’d love to see google do something similar to android for desktop use!

    Seems plausible to me since they picked up some of that team, and with Google’s resources they could make it better. Theirs the demand for android on the desktop but I don’t think it works in its current form

    • Guest123

      any OS can work as a “desktop OS” if it has the necessary apps — apps are what matter, the underlying OS is generally irrelevant for average consumers however, that’s different for the enterprise.

      • Shark Bait

        Yeah symbian would be awesome on my desktop!! (lol)
        Work still needs to be done to make it more usable, first you have to get to the apps. Also the frameworks that that upscale phone apps to a tablet layout will need to be changed to make it suite a desktop layout. And could you imagine not having side by side apps on a desktop??

        • Guest123

          yeah, I can imagine not having side by side apps. . . so can apple ;)

          Most people (yes, they’ve done studies) work on one thing at a time, what’s important there is that you can switch back and forth quickly and have apps running in the background.

          There’s people that already use android as a “desktop” via their phone — some good youtube vids on it. . . it’s all about mindset and what you need to get your work done.

          • Shark Bait

            mac runs apps side by side i dont get that part.

            Im not saying android cant be used as a desktop, and i understand that the apps make a big difference.
            What im trying to say is i dont think android is the best for desktops, it needs some more work, and some fine tuning to make it a more flwaless experience. At the moment it works, but it isnt easy. Things should just work!


            i particularly like the idea in this concept, and i think it would be a great addition for android, not just on the desktop, but for tablets too

          • Guest123

            “best” = personal preference ;)

            Windows certainly isn’t optimal for average non-techie users — far too much to handle on upkeep. Chrome OS works well for many of those people, however Android offers more than Chrome OS and is still relatively easy to use.

            The problem you are having with this idea is, *you* don’t think. . . but that’s just it. I might not like Chrome OS devices, that doesn’t mean they won’t work perfectly well for X% of consumers. Same can be said for Android, and a “desktop launcher” can do a lot, not to mention windowing software. It’s all relative to the particular customer. . . why not through it to the market and see?


          • Shark Bait

            yes this was only my preference, what i would like to use. And im techie, and i hate windows for all the settings and BS, and love chrome OS for just working!

            Nice video, like i say android is usable on a desktop, and their is demand for it too. Id just like to see some more tweaks to make it work better. A few things, like the open with which app screen is massive there, and the notification tray is wasted with that much space. I think it needs tweaks to make it more comfortable and more usable, then it could really take off, especially if their was a full chrome browser in their for chrome apps too!

            would you seriously be happy using it as it is?

          • Guest123

            I plan to go all Android this year :)

            Sick of Windows, and don’t like apple’s stuff at all. Not supporting either of those companies any longer — they’ve done some things I just can’t support.

            I’ve read about some business men who have gone totally mobile and as they put it, you just have to drop the “old mindset of a desktop and adapt to mobile.” And after a year they said no way would they go back. You can always log into a virtual machine, though I don’t think I’ll need any of that — dropping all my “windows required” stuff. And in all honesty, I think my life will be less frustrating :)

            I’m keeping an eye on Ubuntu Touch. . . though I think I’ll be going all Android for a while first. Looking for a new ~6″ device right now. . . one recommendation the people I’ve read who went all mobile said was, bigger device is better.

            Adapt or die!!! :)

          • Shark Bait

            Wow that will be interesting. I would certainly love to ditch windows, and I it too could never use apple. I have tried in the past but my work keeps bringing me to windows only applications. Although windows is strictly a work thing for me now, if i was rich and disnt have to work, My chromebook, chromecast, nexus 7 and nexus 5 would do me fine!

          • Guest123

            lol. . . well, I’m cutting back on the tech stuff I do. .. so, it’ll now be easier.

  • H8win8

    Can you delete Windows and install Chrome OS?

    • Alexandru Florin

      Chrome OS is useless..

    • Nathan Powell

      why when it already has Android(which is a Google OS?

  • Dominik Ladoš

    i think that the Benchmark score in antutu will be very very very high :D

  • droidtomtom

    Wow finally! and an easily justifiable starting price too! Can’t wait to see more specs.

  • Stefan

    I wish it had a decent GPU in the dock.

  • Rajvir Singh

    Asus Y U No use 4.4 :/

  • Cal Rankin

    Does this come with the dock? If so, $599 is good starting point. What are the starting specs? Hopefully they match the iPad in storage.

  • Francis Nguyen

    SO happy, looking at the specs now, no need to upgrade from my SSD upgraded Trio :)

  • Eric

    8gb of ram and Id get it.
