Addressing your two points: 1) One device that does everything will work well if it does everything well. I can take a laptop anywhere and have a usable computer just about everywhere. A phone dock works in locations where you visit often and have a dock, and I wouldn't trust docks in locations I don't control. If I want to work at a coffee store or in a car I can't use a dock. 2) Human design needs to be centered around humans. Humans are designed to rapidly take in lots of information through vision. Designing a device that removes the primary interface between human senses and the device is making that device significantly less useful. I would guess that 90% of the time I spend on my phone is spent reading. I don't want to be read to, but I already have that option if I want. Purposely ruining the device UI and its primary purpose in an attempt to reduce "phone staring" is directly hostile to users. Any sort of general computing device should have the ability to engage directly with your most detailed and useful sense.
