Why? It's certainly different, and I'd expect a learning curve. But if I
were given a chance to swap the 430s I fly (in 4 club aircraft) for 480s,
I'd leap at it. Ignoring the feature differences, there's one UI
difference - entering flight plans just as they're described as IFR
clearances - that's *extremely* desirable in my opinion.

But I'm curious why you disagree.
