I read somewhere the emb had 32" pitch throughout the cabin. Doesnt really matter, they probably are there to stay for a while yet.
If it isn't full though and it makes money, doesn't that mean it is the right plane for the job regardless of pax thoughts. I'm sure most people taking a taxi would prefer a limo.
Regards to the rest, you obviously have more experience than me so you must be right. I like the emb though, except for the valet thing.
