The real problem is that too many people believe that everyone needs the feature set of Exchange. If you need the feature set of Exchange then perhaps you should be running Exchange. Some might prefer the extensibility of Notes. Some folks find that their needs are better met by Citadel, which is a cross between a groupware/messaging and CMS (and is 100% GPL, by the way). Others might like what Cisco is going to do, which is to take the WebEx style of presentation and add groupware features to it. We definitely need more diversity here. It's a fallacy to assume that an Exchange killer has to be an Exchange clone (which is what brands Z and S are doing -- badly).
