Ya that's how I felt the first time I saw it too. The 7-day free trial is what got me. I used it constantly for those 7-days and was really sad when it was over. Now it's the unconscious first place I start for any new idea, be it a new app, website, page, feature - whatever. Start a new mockup, put a text area on the screen and start typing my ideas into it like I used to do with pen and paper. If the idea gets beyond this stage I just start dragging and dropping. What used to take hours with an awkward combination of Asana/Photoshop/pen&paper now takes a fraction of that with far more iterations and better results. Can't sing the praises of this product enough. However: there are many free alternatives if you just want the ability to make wireframes and don't need something great/wont use it often: http://moqups.com http://moqups.com is the latest I've come across. There are lots more.
