At Asus, we already saw that they can combine Android and Windows OS thru the Transformer Duet and the Transformer Trio. This time, all that you can imagine for the size between the 2 OS can be possible, 5-in-1 style.
Introducing the Asus Transformer Book V. Yup, as I said it – it can do in 5 modes: Windows laptop, Windows tablet, Android phone, Android tablet & Android laptop. Such a cool 5-in-1 device specially when you are already intacted to Android and Windows. 
The device has a Android phone and the Windows tablet with keyboard. Based on the video ad, you have to put in the Android phone at the back so that you can use the Android tablet and laptop functions. There’s a dual boot physical button at the keyboard so switch from one OS to another.
The Android phone itself has a big boost as it also has Intel Atom processot and LTE connectivity
