So the radios are hard to work on the 480? I heard the 480 was a lot harder
to learn

I don't think "a lot" is warranted; I could figure out how to do most of
what I wanted to do on the 480 without manual-reading and found it
reasonably intuitive, though the 430 makes the basics more obvious. On
the other hand, if you want to use the full functionality of the box I
like the 480 better than the 430; I think the flight planning functions
are more logical.

Physically, the 480 has a larger screen than the 430.

I gather there are places where /G aircraft can actually get direct
clearances instead of airways, but not around here; having airways saves
a bunch of twiddling.
