The shift to PowerPC was a lot better received, because Apple were already using a Motorola CPU, so using one developed by Motorola and Apple (and IBM) was seen as an upgrade. (And of course, it could emulate 68k code faster than any real 68k CPU could run it, so it was a big upgrade).
In contrast, when it was first announced that OSX would be running on Intel's x86 CPUs there was much wailing and gnashing of teeth, and lo, they did begin to doubt the word of the prophet Jobs and curse the name of Intel.
