Diesel -- you are right on the APU. I do miss it -- but at approx. $1500 per hour difference x 100 hour per year - I would rather have many more flying hours. And I do regularly do to a number of airports where the plane is not on a GPU. I an just slightly under 6' tall -- I do not notice the difference - it must be the configuration because I never liked the Encore/Ultra. Plus the general configuration of the cabin is better if one flies with 5 or 6 pax -- (a) there is more leg room in the 2 seats behind the club seats, (b) catering storage is much, much better, (c) the life raft is integrated in cabinets instead of being strapped to an empty seat, (d) power outlets at every seat, and (e) and now with the iPads, a better entertainment system. So from my seat, I prefer the Phenom to the Excel and it is a good bit less expensive.
