I prefer the checkmark by far, (Never even SEEN a
boing logo on Commodore hardware, was it more a European thing?)
Ok, so this is not on hardware as such, but I found this on
The Commodore Billboard -
Commodore Amiga advertisment which features BOTH the 'Amiga boing ball' AND the 'Amiga rainbow tick'.
I always prefered the rainbow tick personally, to me it's sort of a seal of approval - it implies a pass, or perhaps a thumbs up.
