Joe Wilcox, over at the Microsoft Monitor blog in the post Microsoft Monitor: What is Life Changing?, makes the following observation (bold mine):

Microsoft has a history of releasing products that sometimes are hard to categorize or to explain. Outlook combined e-mail, calendaring, contacts and forms, something totally new in 1996. And the approach made Outlook difficult to describe. How about InfoPath? People still don't really understand what it is. There's a presumption that somehow InfoPath is a forms product. Well, yes, but absolutely no.

Looks like we've got some work to do.
