I would get one simply because it's tablet sized and I can use it as a tablet or a laptop with full Windows functionality, therefore easy portable gaming of all sorts.

There is an older generation of technology called tablet laptops or table laptop hybrids, which are basically a full sized laptop that often doesn't have touch compatibility and its main feature is really that it's monitor and can swivel and make it seem basically like you're holding a screen in your hand.
The new term coined by Intel "Ultrabook Convertible" seems to fit these specifications:
smaller than a laptop around 14" and under
Thin as an ultrabook
A screen that swivels over the base part of the notebook to make it into a touchscreen tablet
Can run the full version of Windows 8, therefore you can switch between having a more convenient tablet experience or a full Windows enviroment.
