Guy I know joined onto the Phenom in the last 18 months. He enjoys it and it's sports-car like handling and flying qualities. Flight deck is super automated if you like modern/advanced cockpits. Tours offer great variety of flying so far for him - he hit all 4 corners in the last tour with good hotels (although min rest on several layovers). And he loves knowing his schedule after years flying 135 charter with no real schedule - the opportunity for a schedule is a big improvement for him and was one big reason why he applied.

He likes the airplane, the performance, the variety of flying, lack of a commute (East Coast domicile with plenty of airline options to get to his airplane on Day 1) and his fellow pilots. The challenge for him has been the length of some legs in that relatively tight cockpit - some flights nearing 4 hours. Also, he has come to the realization that an opportunity to bid to a more ergonomic/comfy airplane is a ways off... 3-5 years or longer? Upgrade time also looks long - maybe 10-15 years... Take a look at this picture:

Not every leg is a long flight. However, this airplane is very capable and it can fly 3-4 hours easily and the owners know it. I am not sure the XLS is much of an improvement after 2-3 hours in that cockpit either.
