See XEP-0160 - these days, people expect simple messages to persist  
and be fed to them when they come back online.

Incidentally, XMPP on smartphones - well, on real smartphones and not  
those which place shiny over substance - does mostly the same thing  
as IMAP IDLE - it maintains a long-lived TCP session which both ends  
can use to push data over. On shiny but castrated smartphones,  
though, a developer must buy in (technically at least, financially I  
don't know) into a proprietary unified push system. Which, rumour has  
it, runs over XMPP, using a persistent TCP connection...

It also handles Big Things, and - when IMAP's in play at least -  
offers excellent server-side archival under the user's control.

It's not mere traditionalism that we're having this conversation over  
email and not in an IM chatroom, after all - even the XSF uses  
mailing lists.
