I've had it sitting in the hangar for half a year until I had the guts to dive in...
IMHO that initial step is steep not because of the aircraft's systems but because you have to learn the FBO, the walking (and ducking!), operating a door etc. Then you never know if you'll fall out of the sky if you forgot a step (do I have to do the flight planning in the FBO? Do I have to take passengers?). That might sound ridiculous but that was what intimidated me. Once you prepared the aircraft from the outside and fueled it this can be a very smooth experience even for newcomers.
Now after many many great flights I just immediately click the door at the end of the FBO lobby, have configured the 650 not to overwrite my go-to-cockpit-button (W!) and can hop in directly.
I never put on the chocks, pins and covers, discovered how to fuel from the inside and am now REALLY enjoying the stunning avionics and depth of the systems.
Just sayin'. The FBO is a neat idea. But a "Skip to cockpit" and a "Perform walk-around actions" in the menu would be much appreciated.
Re: Saving airframes: while gives you the state you left it in (which helps), it is not the same as being able to save and recall states.
