Admittedly, software that's influenced by the iPad and iPhone, so there is new software, but it's not that new. Multitasking in iOS has been a thing for a while (iPad).

I'm not trying to discount the efforts involved here, just pointing out that they aren't starting from scratch. And much of the required features to support a dual-screen (triple-?) phone has been in the works for a while.
