If you use your PC the most that's fine just put that, but what about your game consoles?
I haven't really used my games consoles in ages, and the last one was the Wii U a couple of months ago - I would probably say I use my (3)DS the most as it's just convenient with it being portable - sometimes I can lose track of time though and end up playing Pokémon for hours, but luckily I haven't done that in a few years.
