Rumour is that TT is very supportive of the business seats and that it will take a small nuclear device to change his mind and to lose face.
The Virgin ones work. They are wider, angled more so you don't get you feet knocked by people walking past and are made of superior materials. Ditto the Air New Zealand ones, altogether a better product with more solid construction. CXs are like a Ford America interior, the other airlines' are much more Mercedes.
The privacy/ sociability aspect is the biggie. A bunch of responders to inflight surveys said they wanted privacy so the airlines went that way, ignoring the 49% who wanted to converse.
Why not a dagger board system like on the old First Class? Too complicated, too expensive (huh?) and too heavy were the answers given.
One day we will have seats designed by people who can afford to fly in them.
