Sway is still in preview, but it is already one of my favorite tools. As a teacher I see huge educational opportunities and as a web designer I like the ease in use. Sway revised the way of publishing and presenting content. It allow to create, present and share and is available to all platforms and devices. A sway is responsive (mobile devices) and ready in a blink of an eye. Sway allow to flip your classroom. Oh, and it's free.
