Imagine if you could ship your desktop app in a natively running virtual machine, that is as perfect as it gets from sandboxing code and running a lightning fast JIT compiler instead of virtualization. It delivers a common user experience, digital accessibility, endless customization while being secure, it's free for developers and users, constantly updated and it delivers an absurdly powerful, while also perfectly printable markup and styling engine.
That's what a browser is. Your apps are native.
