Focusing more on the "social side" rather the HW part, there is the part about the "Viral email", which must have been something that went viral in the UK Internet circles but not outside (I don't remember it and Y2K Internet was much smaller). Investigating about it you can end up reading The Register "article" about it [1] and well, that's something that definitely would not be published nowadays. Names and surnames of all the people involved in it, the literal sentence of the viral email copypasted there. It really shows how a different time it was regarding privacy and personal data.

EDIT: I mean, things like this obviously keep happening nowadays in closed (and not so closed) social media circles, but you won't see an online publication putting down names in written form like that.
