NEW YORK ( TheStreet) -- What do Certs, the breath mint, and tablets have in common? More than you think.

Certs was promoted as both "a breath mint and a candy mint with the tag line "It's two... two... two mints in one".

Asus has announced the computer equivalent of Certs mints, unveiling the Transformer AiO. It's a desktop computer that runs Microsoft's ( MSFT) Windows 8 - and a large tablet which runs Google's ( GOOG) Android OS.

It's two... two... two computers in one!

The AiO, which stands for All in One, is two different computers built into one device. The desktop configuration runs Windows 8 on a third-generation Intel ( INTC) Core processor, from 4 GB to 8 GB of RAM and as much as 2 TB of storage when it's running the 64-bit version of Windows 8.

However, when you take the gigantic, 18.4-inch (1920 by 1080 pixels) LED touchscreen out from its desktop dock/stand, the AiO turns into an Android tablet. It runs Android 4.1 (Jelly Bean) OS on a quad-core, NVIDIA ( NVDA) Tegra 3 processor, with its own 2 GB of RAM and 32 GB of onboard storage.

At first glance, the Transformer AiO poses more questions than it answers. Among those that immediately come to mind:

A 5.3-pound tablet with an 18.4-inch screen? Really? Why would AiO run Windows 8 and Android, and not Windows 8 and Windows RT? Why even have a second operating system at all?

I'm sure we'll get some real-life answers to these burning questions - and many others - in the near future. Asus is promising its heir Transformer AiO will become available in North America as soon as the second quarter of 2013. The device will sport a price tag of $1,299.
