I like the 1-2-1 layout, as it beats the 2s that UA employs in its aircraft.
Love the PE as well, since that is what I'll travel in most of the time. I wouldn't want to be the middle seat mate, though.
Looking forward to the 787's arrival, and have been checking that 787 blog for the latest on production updates. Will need to book a few vacation days when they start the short haul "test flights".
