Actually the 68XX family was used in the original Apple Computers. The 68XXX was used in the Mac. The new Mac's use the Power PC chip.

The original Apple computers used a Rockwell 6502 chip, which is really quite a different beast than the 68XX parts.
For Microcontrollers, the 68HC11 is a very popular chip, but is being phased out. The 68HC12 is the 'replacement' series for the HC11. Programming architecture is nearly identical, but the HC12 is a 16 bit core with quite a few improvements.
The 68000 series are the parts for the original Mac's. Aside from the 68 at the start of the part number, they really have nothing in common with the 68HC11 or 68HC12.
Motorola's current 8-bit part is the 68HC08 which is aimed to compete with the PIC from Microchip. The 68HC08 core is again not really compatible with the 68HC11/12 parts, but is a good chip.
I would, in my opinion, avoid the PIC and select a better series of parts, such as an Atmel AVR or perhaps the 68HC12.
