Responsive Design - Creative Concept Design Discussion (What software do you use to manage all those device layouts?)

Trusty old photoshop and illustrator don't really cut the mustard with creative concept development for responsive websites. A basic site with 10 pages and say 5 breakpoints would need 50 files/layers! Fireworks and Indesign(???) both have people supporting them and then there's lots of folks actually designing in the browser. (Boston Globe was designed in Indesign)

Let's talk about what we're using to do creative layouts for responsive websites. Also presenting the creative to clients has a new twist with responsive design.

If you can, bring some files for show and tell.
