I really consider the italic 'AMIGA' to be the most enduring of the logotypes above. It's appeared on every bit of Amiga hardware I can think of...

CDTV (basically a black 1011) has that italic 'AMIGA' embossed just above the disk slot. The old 1010, despite only sporting a rainbow tick on the front,
does have the italic Amiga writing on it.Edit: You can also see it
here on Chelsea Football Club's old shirt.
It's always seemed to me that part of having an Amiga (given my experience only with the 'wedge' models) was that embossed 'AMIGA' just above the disk drive, next to the power / disk access LEDs.
