I still use the word 'cyberspace' sometimes, just like I do with the term 'real life', but mostly in general (philosophical) discussion.
For example, a discussion about the difference of human behavior between the real world and cyberspace. (and God knows what else comes up on late nights with nerdy friends)

You are certainly right though that, ever since Facebook, online banking and what not, those terms do not carry a lot of meaning anymore, especially towards my non-techie friends
