Notes is itself pretty remarkable, but suffers from a peculiar UI + dysfunctional efforts from two sides in development (people who wish it was a RDBMS not a document database, and people who don't really have any business writing application code). The complaints about it being kind of an ugly email client are not really of the essence. In addition, IBM has pretty much left it to rot on the vine since the early 2000s. I think "R5" was the last release of any real significance, and even that was not revolutionary.
