Asus Transformer Book Trio combines Windows and Android – but what is it for?

Microsoft has one idea about how to combine desktop Windows with a tablet OS: mash them together into a single operating system and call it Windows 8.

Asus has another idea. Put Windows in the keyboard dock, Android in the tablet, and allow the tablet to be docket to form a Windows or Android laptop.

This is the Transformer Book Trio, just launched and on sale from 11 November 2013 at £899.99.

All my instincts say this a terrible idea. Let Windows be Windows and Android Android, do not try to combine them.

Trying the machine though I found it was good fun. Just press the little Android button and it switches.

and it becomes an Android laptop:

The dock mechanism is a bit ugly but looks robust:

There is the question still: what will you do with the keyboard when not in use? In a home context that is not a problem, but when on the road I find the most convenient place to keep a detachable keyboard is to attach it, making it more of a laptop than a tablet in practice.

Having two computers in one gives you a few options, which I did not have time to explore in detail. As I understand it, you can share storage in order to open a document prepared in Windows on Android, for example, and with two batteries there is scope for charging one from the other.

This is two separate computers though. It should really be called Duo, but Asus calls it Trio on the grounds that you can use it as a laptop or a desktop machine, with an external display.

The PC runs an Intel Core i5 4200U, and has 4GB RAM and 500GB hard drive. The display is 1920 x 1080 and supports capacitive 10-point multi-touch. Connectivity includes 802.11ac (dual-band) wi-fi, Bluetooth 4.0, 2 USB 3.0 ports, Mini DisplayPort, and Micro-HDMI 1.4.

The tablet has an Intel Atom Z2560 with 2GB RAM and 16GB storage. Connectivity includes   802.11n (2.4GHz), Bluetooth 3.0, Micro-USB 2.0, microSD card slot.

Fun then; but what is the use case for this machine? This is where I am still having difficulty. It is somewhat expensive (though with a Core i5 performance is decent), and I have a hunch that users will end up sticking with one or the other OS most of the time – probably Windows given the price.

Oddly, it would make more sense to me to have a high-end Android device with the ability to run Windows when needed. This would address the case where a user wants to migrate to Android but occasionally needs a Windows app.
