I agree with your sentiment entirely! One thing to point out - the ‘long slow travel while working’ mode is still possible even with tin cans. To wit:
I just had one of my most focused, productive (and enjoyable!) coding sessions of my life on a Zurich -> SFO flight. It was a day flight, 12 hours long. I was lucky enough to have a bulkhead seat in economy and conditions were perfect - it was dark (enough), I had absolute focus, unlimited coffee that got refilled automatically ;) snacks, meals, zero phone calls/distractions, and good-enough WiFi. I’ve never felt 12 hours vanish so quickly (and code appear so fluidly ;)
