It could well offer fewer features, presented from a useful alternative perspective and without the old method's social baggage.
Having said that, my first instinct upon reading this feature list is to suspect that you're right. Yammer has too many of email's features. They need to leave more things out. Otherwise the pathological behaviors that characterize corporate email (poor composition, unclear expectations, inbox overload, endless chains of quotations, complex workflows, reliance on cut-and-paste versus publish-and-link, the use of Microsoft Office attachments) will just port right over, and nothing will change.
I'm guessing that removing the character limit will prove to be an especially foolish design decision: Who wants to read five-paragraph Tweets? And file attachments are probably even worse. One of the charms of Twitter is that it refuses to allow such dinosaurs. Instead it forces you to adopt an amazing modern technology -- the hyperlink -- to point people at your blog, or your Flickr set, or your Slideshare page, or your Scribd page, or your github account.
