Family computer was... well... I can't remember much. All I know is that it used DOS (I think), it used floppies and we were using it in when Windows 98 was out. I remember one which used the big ol' floppies, but that may or may not have been that one.
The one which actually belonged to me? A little before the Wii came out (I think) I got a laptop with Windows 2000. Pathetic little thing which couldn't run any games, really. Got hot real quick and it rarely connected to the internet. That died due to what we now think was a poorly-fitted component, but we don't care anymore. It was cheap.
