Bought a Honda Accord Hybrid on December 9.
I only have a couple hundred miles on it, but the display shows around 28 - 30 mpg in city driving and 38 - 40 on the highway. Will add to the mileage database when I have data.
Initial driving impression is that are only minor differences between the hybrid and the regular Accord.
I have, however, ordered a "mini" spare tire since Honda provides a small air compressor and can of sealant as standard equipment (to save weight?).
