Also the fast and steady technical invention of new web and interface controls (just imagine how Apple’s iPhone has influenced user behavior in the web), make it hard for the interface design tool providers to keep pace with development of the latest controls and a natural lag until these controls find its way into the wireframing applications is imminent.

But imagining the funny fact that these new and behavior breaking controls also have been developed and tested with interface design tools like the ones described here, the future looks bright for digital interface prototyping.

So we only can recommend testing these interface design tools since they all offer free trial periods of some kind. As a good example of what’s state of the art in the field, we have listed a completely web-based wireframing software with many interesting real-time collaboration features in the resources box.
