crapware?
As a Notes user who was forced to switch to Exchange, OWA and Sharepoint I can without any qalms say those 3 are the epitome of crapware. Sharepoint even today isn't to the level of sophistication Lotus Domino was in 1998. And complaining about the Notes interface is silly. It's completely customizable, unlike Outlook. Heck, if you want, you can even make it look and "feel" like Outlook.
