Following on Canonical’s convergence dream for Ubuntu Linux, Purism made the convergence dream a reality for its PureOS Linux operating system that ships pre-installed with all Librem laptops, as well as the upcoming Librem 5 Linux phone, allowing users to use a single set of apps on both mobile phones and laptops. Since GNOME is used as default desktop environment for PureOS, Purism is also working hard on creating adaptive ???GNOME??? apps that look and work great on both mobile phones and laptops. Purism says that convergent apps will also be a lot easier to maintain and secure than having separate builds for mobile and desktop.
