The fun fact is, that when Purism write convergence, they‘re after what Canonicals' Ubuntu Touch (which sadly is not mentioned at all in the post) meant with Convergence and what Microsoft called "Continuum": Plugging your phone into a laptop dock or a monitor, keyboard + mouse and be able to use it as a "proper Computer". This requires "convergent apps" which change menus and sometimes even add features when they are run on a larger canvas of pixels. It's supposed to be even more in one device.
