Arc is an indomitable name. It's short, memorable, recognizable, and pronounceable. It's also a strong prefix: Arc app, Arc box, Arc sync, Arc OS, etc.

Arc passes the highway test with flying colors. Imagine driving down the highway when an 18-wheeler thunders past. If you remember the name stamped on the side of the corrugated shipping crate, it's a good name. 'Arc' in a Neo-grotesque typeface next to an iconic logo on such a shipping crate is as good as burning Arc into your retina with a megawatt laser.
