I think one advantage of air travel is it's distracting. Busy flight attendants, announcements from pilots, plane moving to the runway, taking off... so there's less reason to concentrate on the lack of space while stuck in the seat.

I'm sure the seatbacks would all have some net connected display for movies or actual computing.

Are you? I wouldn't rule it out, but personally I think getting an outside signal into a sealed capsule which is moving so rapidly that it must use battery power rather than a physically connected power source seems more than trivial.

Nah, wifi would travel great in a long metal tube.

For 300 miles? Or are you proposing spacing hubs out along the journey, in which case, wouldn't frequent reconnection be an issue?

You can yak on your cellphone (or watch movies on your tablet) for the entire 35 minutes of this journey.

His proposal includes "entertainment displays", so there is some sort of built in distraction technology.

In this case it looks like you could have a great view.

What do you mean? Hyperloop capsules have no windows.

Not to mention the tube is steel, which isn't traditionally light-permeable.

In THIS case. What if this becomes standardized and more routes are hooked up?

Great point.
