You might think that CES 2014 is the first place where 2-in-1 Android Windows PCs have been displayed. Well, they've been in the pipeline for some time, and now they're being showcased at CES as full-fledged models that run on two operating systems.

At first, the 2-in-1 concept might sound like a buy one, get one free deal. But there might be some hiccups when you try to merge two different OSs in one personal computer.

The Verge was the first to report when Intel outed news of its dual boot personal computers. Intel is capable of powering dual Os and it can switch between a Windows and an Android at the press of a button. Asus too has a laptop on display at CES that uses the technology.

Using a different model with Android apps and a Windowss PC, AMD has unveiled its version of the 2-in-one.

The Seattle Times reported that AMD and BlueStacks are collaborating on a Android Windows system enabling the launch of Android apps in the Windows configuration.

What did Microsoft have to say about being included in a joint effort with other computr makers. Here it is: "Regardless of what you boot, we remain focused on ensuring that the best experience for device manufacturers, application developers and consumers on any device is Windows."

Asus Transformer Book Duet, using twin operating systems has been launched at CES last week.

When you ask around about who might be interested in a device like this, analyst at Directions on Microsoft, Wes Miller told the Seattle Times, "this is definitely a power user feature," adding, "This is not a feature that most consumers would be comfortable using. If that's their target audience, they're off by a mile."
