I am excited to see more application options in this space. Adobe has achieved a monopoly in creative circles with their applications, specifically Photoshop, Illustrator, and InDesign (and for a long time Flash and Acrobat as well). Flash is a great tool but the format was never really opened to other applications and now it's losing to HTML5. I do credit Adobe for opening up the PDF format, and it would be great if more standard formats could win out regardless of the application that created them.
