As a member of the current generation, I know that I don't often send personal emails. And yes, it's something my parents and teachers use.

But I definitely use it to talk to members of the older generation. And anything that's less than personal, in fact. Any sort of business arrangements, anything that's supposed to look professional.

In fact, the lack of time constraints on email make it far superior to most newer technologies for anything that requires some thought. Email gives you a chance to (re)consider your argument, idea, or response. And to spellcheck.

(Irony: Firefox spellchecker picked up "spellcheck" as incorrect. More irony: "spellchecker" is fine.)
