The ultimate state is Wolfram walking around in the woods with a laptop harness:

Kinda hoping in the next decade or so we'll get good enough augmented reality that we'll be able to walk around in the woods with a floating terminal. Maybe a chorded keyer for input.
Wolfram has also had that hope, according to the linked article:
> I’d actually been thinking about walking and working for a long time. Twenty years ago I imagined doing it with an augmented reality display and a one-handed (chorded) keyboard. But the technology didn’t arrive, and I wasn’t even sure the ergonomics would work out (would it make me motion sick, for example?).
