"Rails might just be a better fit for today's Mac OS X developers than WebObjects.".Rails is probably very nice but the Nextstep revolution was the tools like interface builder. The scripting developers and rails developers specifically seem to turn away from that and use the language more.I think cocoa and rails are therefor at two oposite sites of a debate and not comparable. I do think webobjects is going to have a hard time competing with jsf and sun studio creator.
