 Hi guys, Vlad with The Verge, I'm here at CS 2014 in Las Vegas and I'm taking a look at the brand new Transformer Book Duet from Asus. The company describes this as the first 4-in-1 device and the reason it says that is because it's a Windows laptop, an Android laptop and an Android tablet and a Windows tablet. There's this OS switching button, it takes approximately 4 seconds, says Asus, to switch between Android and Windows. And now we're looking at the Android UI and if we press the button again we switch back to Windows. Now Asus won't really tell us how it's doing this but it says it's one of the first genuine Duo OS devices. It says it's its own proprietary technology that it's using. I've been taking a look at this, it has a 13-inch display. Looking at the battery, when it's docked into the keyboard dock I get a promise of 10 hours initially, now I'm getting a promise of 6 hours so that's not terribly reliable. But anyhow, the important thing is you can undock the display from the keyboard and then what you're faced with is a 13-inch tablet, 13.3-inch tablet. As a full HD resolution, this one in particular, is also a 1300x700 resolution version which is $100 cheaper. That one is $599, the full HD is $699, it will be available at the end of March in the United States as well as globally. The processor inside is an Intel Haswell, it goes all the way up to Core i7. There's no webcam or any camera on the back, there's a front-facing camera at the front which kind of really makes sense because for such a large tablet or laptop, however you want to look at it, you're not really going to take a lot of high-resolution shots. In terms of storage, you get 64 gigabytes in the tablet or 128 gigabytes, again that's probably going to raise the price of the device and also in the dock you can get 320, 500, 750 gigabytes or a terabyte of storage on top of what you get in the tablet itself. The display is an IPS display, quite traditional for Asus. It's relatively thick, we've got a selection of ports down here at the bottom, headphone jack, docking button, there's a power key. Hello, and that brings us into the windows, well actually it's not a power key, it's a windows button tucked away at the bottom. So this is the first 4-in-1 device as Asus describes it. It looks good, it has that concentric circle design on the back and it is quite intriguing. The always switching is indeed very quick but we'll need to spend a bit more time with it to get a good idea of how useful it actually ends up being in practice. So first look at it here at CES 2014 in Las Vegas.
