I used Muse during the private beta and found it to be a refreshing take on free-form note taking. I've yet to figure out how to incorporate it into my workflow, but I'm very, very happy to see a passionate team working on fluid, performant software.

The gestural interface and limited toolset made it easy to focus on taking notes and arranging thoughts rather than "fighting the program" and wasting time choosing between dozens of pens and colours.

Best of luck with the launch!
