You would imagine that Valve has its ‘Steam Machine’ concept only for desktops, but that’s not entirely true.
It seems that Valve (or someone else) is working on a handheld device called ‘SteamBoy’. The device seems to be having the same touchpads that the Steam Controller has, along with a 5-inch display. It also shows that there are 8 action buttons with 2 more buttons on the rear and 4 triggers.According to The Escapist, the device is a quad-core processor most likely using either Intel Atom or an AMD A4, along with 4GB RAM, 3G support and a 32GB onboard memory. As of now, its assumed that this handheld steam gaming device should be ready by 2015. As of now, there’s only an E3 teaser video.
A representative mentioned that SteamBoy won’t be as powerful as Steam Machines in the same way Nintendo 3DS and PS VITA’s performance cannot be compared with Wii U or PlayStation 4. The press release points out that the SteamBoy will be the first device that will allow to play steam games on the go.https://www.youtube.com/watch?v=UM63RuEhgHU
