As kube-system said, Motorola had this, and Microsoft phone also tried to fill this niche. Personally, I would love to have everything in a phone, with a good docking system for my desk, interop with a living room large monitor, and of course supporting all the dev setups that I use. After seeing what functionality Apple packs into their Apple Watch, it seems like the tech exists for a ubiquitous phone device - if only there was a large enough market so a company like Apple, or a Linux based phone company to build it.
