I certainly don't care to defend the original Apple mouse, but another example of revisionism is the idea that "journalists" of the time were aghast at how bad it was. This was 1984. Most "journalists" had never seen a mouse, let alone used enough to be critical of a specific implementation.
The introduction of the Mac caused everyone else to go out and start building mice, even if you couldn't really do anything with them. Fortunately, those other people learned from Apple's original design mistakes (sharp corners, ouch!).
Yes, the original MS mouse shipped about 6 months before the Mac 128K--remember that MS had Macs before the public did--but few sold as there wasn't much use for a mouse in command line MS-DOS. And the design was nearly as bad as Apple's.
(I'd claim that the original iMac "hockey puck" mouse was an even worse design. No sharp corners, but you couldn't figure out which way was "up" so were always mousing at a diagonal.)
