Dolphin's aimed at traditional app development --- you can use it to produce standalone native-look-and-feel apps which you can deploy separately from the IDE.

Dolphin's aimed at traditional app development --- you can use it to produce standalone native-look-and-feel apps which you can deploy separately from the IDE. (Although I suspect that what you get is a minified VM image and a runtime rather than true offline compilation.) I believe it has a decent following in banking and stockbroking environments, presumably because Smalltalk's traditionally good at RAD and it lets them knock out database frontends very quickly. Certainly, whenever you hear actual customers talk about it, they all seem to like it.
