The IxDA forum has a thread going about the merits of using Adobe Fireworks for creating wireframes and rapid prototypes. Fireworks is my tool of choice for wireframing/prototyping and I still get looks of surprise when I tell other UI designers this. I think a lot of designers view Fireworks as a image optimization tool, which I’m sure it’s still good for. But Adobe has done a really good job of turning what was a slightly redundant part of its Creative Suite (redundant to Photoshop and formerly ImageReady) into a piece of software that fills the much needed gap of wireframing and prototyping. I’ve looked into other solutions such as Axure and Visio, but it’s hard to justify the cost of an additional software package when I already have Fireworks via the Adobe Web Suite.
