Wow that's really impressive considering that the original PS4 is already very small.

I wouldn't say that OG PS is very small, Wii is what I call very small, but yes PS4 lota smaller than OG XB1 even it has stronger hardware and integral power, PS4 is very well designed console (exept nose and heat). PS4 Slim is day one for me.
