I would _much_ rather be programming 680x0 processors, and had their speed driven by the market pressure that has driven Intel. Programming the 680x0's feels just like programming any well-done architecture of the early 80's... lots of instructions, lots of registers, sane instruction formats, sane memory addressing modes, etc. None of that early segment horse- hockey. :)
