I've seen "no chat interface" come up in multiple gmail/fastmail comparisons, and I'm genuinely confused as to why. Do people expect email to come with a chat client? It seems weird to me to have email + xmpp/hangouts merged together and not separated (I use Adium, for instance). Email contacts are rarely people I chat with, with the exception of my innermost circle who I contact with pretty much everything, whichever fits best at the moment.
