Idk, a tv experience where you can potentially play xbox, Sony, steam, and whatever other games? If it runs more easily than running pc thru a tv, its gonna have an audience.So it's a console without the benefits of a console (price, exclusives, physical games) and a PC without the benefits of a PC (raw power, customizability, upgradability). I'm sure the number of people this appeals to is...non-zero, but is there really that much demand for something like this?
But then, what do I know? The value proposition for portables is similarly baffling to me for most use cases, and those seem to be getting popular here.
