Its got terrain warning, traffic alert (when mode 'S' is implemented across europe), contoured moving map, auto ILS alignment and storm scope to name a few features I would call extra functionality over a standard modern IFR fit.
I fly coupled to a bendix/king auto-pilot (which is pretty good and works quite well) but Garmin are developing their own autopilot which, when coupled to the G-1000 will offer so many new features including auto throttles. The new D-jet could have this and possible the Cessna Mustang (even most entry level biz jets dont have autothrust). There is alot of stuff yet to come out of the G-1000...just wait and see

Standard cessna G-1000 set-up
Way of the future? For GA, I would say yes
