Dear Lazy G+, What disadvantages are there from using Google Apps for Business/Domains compared to using @gmail.com? Other that not being able to use G+ with the same login at present.

I am assuming that there's the advantage of getting to use Jabber in Gmail with an @hsivonen.fi identity instead of an @gmail.com identity if I use Google Apps for Business/Domain as opposed to regular Gmail. Is my assumption correct?

Alternatively, is there a self-hostable webmail app that has usability comparable to Gmail? (Zimbra is not it.)
