My wife calls it an Xbox, but only after she started playing the occasional game with me. She usually called it a waste of time, but now she loves to play Lego Star Wars and other Lego games, lol. When I was growing up, everything was Gameboy or Nintendo.
I know what you're talking about. I didn't even have a console until I was about twelve. During that time I would play games on the family computer. To this day (I'm sixteen now), my mom still refers tomy Xbox 360 as "the computer".
