Apple - Intel
This hardly has anything to do with functional programming in general, or Haskell in particular, but I'm a bit upset by the move to Intel processors. It seems to me that going with AMD might've been a more viable choice, at least from a ISA pov. Furthermore, while AMD chips still dissipate more power than Intel processors, the CPU's seem to be much nicer, better designed, and yield real 64-bit power.
Guess I won't be able to upgrade my powerbook status to a shiny G5 in a few years.
