Switch: Tegra SOC, integrated display, integrated controls, flash based storage, and powered by an internal battery.
Shield Tablet: Tegra SOC, integrated display, integrated controls, flash based storage, and powered by an internal battery.
PS4: x86-64 bit cpu, desktop based GPU, no integrated display, no integrated controls, standard HDD storage, requires AC power and external display.
xbox: x86-64 bit cpu, desktop based GPU, no integrated display, no integrated controls, standard HDD storage, requires AC power and external display.
Clearly the Switch is a console.
But then it wouldn't be good to tell investors that you outsold the NVidia Shield tablet, sounds way better to say you outsold the xbox and ps4. What's next, is Samsung going to start comparing sales of their Galaxy phone against Dell computers?
