I need to try this!
I should start by saying I am by no means a Keynote ‘pro’ compared with many of our web team who could use it in their sleep. In fact, when I first started working at ESPI last July, I was very surprised to find out that designers were using Keynote for laying out presentations. My surprise turned to alarm when I found out that they were also using it as a design tool to build UI designs for websites and apps. It turns out that I was absolutely wrong. Keynote is an incredibly powerful design tool. Less then one year later, I now rarely (if ever) use InDesign to layout presentations, and I have started using Keynote almost exclusively for any web layouts I do. And not just UX wireframes, but full UI designs. On a recent project, I also used it for poster mock ups, banner designs and a bunch of other formats.
