If you could write an OS from scratch...

Okay, so most every OS out there is C-based.  If you could magically write a complete hardware-controlling OS all the way up to the UI and applications using a different language, which would you choose?

Though I like Lisp, I think I'd have to choose Erlang, maybe NewSqueak for embedded/smaller systems.

It's just a translation (however complex is it), with macros at best. No stunts pulled behind the scenes. No abstraction capabilities. Thus, not even remotely high-level.

Level: Machine language < assembly < portable assembly (C) < Sepples < Bare Lisp < FIOC < the language I'd implement

require every PC to upgrade to 4G RAM and 5 PROCESSING UNITS
Apply for a job at Microsoft. Also, how fast five processing units really are? Five M68020s? Five Opterons?
