Used it, presented a site to a client with it, love it. The level of detail on design elements is nice, so things can get blocked out without the distractions of too-polished design (i.e. hundreds of icons, custom images). Really appreciated and heavily used the grid update from a few months ago -- well implemented with the minimum amount of UI, like the rest of the app. Highly recommended.
