Unless you want to impose blurry fonts onto your visitors, this font won't be it unfortunately. The required increments of 11px to display a crisp font with DepartureMono makes your content either too small (11px) for most people to read, or too large (22px) to look good.

I am always saddened by landing pages like this, because they communicate an idea that only works in very specific cases. Are you looking to use this font for a similarly polished, "Apple"-style landing page that is form-over-function? Then this font clearly is for you. But on 99% of pages that have actual content on them this font likely won't work, as much as I, too, would like for it to.
