Curio has long been an innovative product, and version 5 continues to expand its capabilities as a creative organization tool. The new web views, and cross project linking are something I've wanted for a long time. The new project organization functions and iCal syncing are items I had even thought would make it in to the product any time soon, yet here they are. This is a great product which is open on my desktop all day every day, and is an excellent example of great Mac software. It isn't OmniOutliner, or OmniGraffle, or Yojimbo, or Microsoft Project, but it is an elegant combination of many of their features, and more. I'm definitely a satisfied user. Can't wait to see where they go with Curio 6.
