The Asus Transformer Book is a great laptop, but users said they would have liked it more if it offers dual operating systems. It looks like the Taiwanese manufacturer has heeded their cry. 

At the CES event, Asus unveiled the laptop's dual OS version, dubbed as the Asus Transformer Book Duet. During its press conference, Asus called it a "4-in-1 laptop and tablet" and runs on both Windows and Android. 

You may be thinking that you need to shut down the laptop first before you are able to switch, but that's not needed with the manufacturer's Instant Switch Technology. In the report by Android Authority, you will be able to switch from Windows to Android and vice versa in under 8 seconds. 

Below are some of the device's 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

From the list of features above, we can see that Asus really plans to make this laptop-tablet hybrid sell. And with a pricetag of only $599, it is really difficult not to give this one a try. 

However, on the downside, the Asus Transformer Book Duet reportedly weighs more than most laptops and ultrabooks, but if you value functionality more than portability, then this might be worth your buck. 

We'll keep you posted for more details regarding the laptop's CPU.
