EPS or PDF are the magic intermediate file formats

When I design interaction flows, I use a drawing program like Visio or OmniGraffle. The challenge has been sharing these files with others. I finally settled on PDF as the optimal solution. The text remains selectable and the drawings retain all of their vector goodness.

Enter PowerPoint. Sometimes you want to present the designs in a click-through format, either to users for a low-fi usability test, or to executive types (investors, advisers, press, etc.). After much trial-and-error, I finally found the optimal workflow. Save out each page as an EPS or PDF file, then import into PPT. All other formats either don't support vector, or they risk degraded fidelity.

It's really too bad the clipboard doesn't work, as it's a PITA to save each mock-up out as an individual file, then insert it into a new blank PPT slide. I suppose I should look into an automated solution for this. I used to be quite the AppleScripter back in the day...
