Adobe sells some of the popular software such as Photoshop, Dreamweaver, Flash Professional and InDesign, which has placed Adobe in a dominant position in the creative software market.
Adobe has held a bit of a lead there with Dreamweaver, now part of its Creative Suite, and a number of SAAS options like Business Catalyst and forthcoming Muse (a code name).
Adobe Edge Reflow builds upon the embryonic responsive design tools in the current Dreamweaver and gives you complete control over breakpoints between different screen sizes, as well as WYSIWYG control over CSS styles and the ability to identify and export all of the relevant bits of code.
