This actually looks more comfortable to me. The biggest issue I run into is bumping knees because I'm in a middle seat with two other people 6'+. This completely solves that problem.
Now the fact that you're looking back at other people's faces like the worst elevator manners is a different kind of discomfort...
Having relatively wide shoulders, the "fight" for the arm rest was always one of the most annoying aspects of flying. This layout would get rid of all the shoulder and arm bumping, which would be welcome.
Why not just pack people into tiny shipping tubes?
