And for the Z80: also that it only needed GND and 5V. The 8080 also needed 12V. And the Z80 only needed a single clock phase -- the 8080 needed two. The 6502 also only needed 5V and a single clock input (the 6800 needed two clock phases). The 6502 and Z80 were simply a lot easier to work with than most of the competition.
