Just to come back in again and say that I basically agree with maxman. What I want from Econ+ is to work or sleep. And that leaves me with three non-negotiable demands:
1. More legroom
2. Lounge access
3. Get into Econ+ with a full price Econ ticket.
The rest is nice but wont affect my purchase decision.
Must admit that I've never flown Econ+. Always either cattle or Business.
