Clemens Vasters seems to really dig InfoPath … some good quotes:
“On the surface, InfoPath is “just” a forms editor that allows you to build editable Forms for XML Schema, Web Services and Databases very quickly. From a technology perspective that’s very cool in itself, but the way InfoPath hides all of that behind its UI will simply make you say “Well, yes, that’s how it should be”. It’s really a no-nonsense data-capture and data-presentation centric variation of what could have been yet another feature of FrontPage that few people would have ever noticed, just because it’s UI is so simple. It’s all Office.”
