I really like the layout. It can make you lazy if you have to go back to a G-IV or the G-V Classic. No more jumping back and forth to the display controller for brakes and flight control system pages. If there is anything that takes getting use to is the charts being displayed. The white border and "paper" of the charts even with dimming is still bright for night flying although I hear there is a fix coming. Another "neat" feature is the ability to do just about everything on the I-Nav, load approaches, intercepts, etc. Just about anything you can do by entering key strokes in the MCDU you can do with the CCD on the I-NAV.
