And when do you need to do that? Quake only uses assembler for software
rendering. Other then that, plain C. 

I can't begin to imagine when I would want to use assembler. Maybe the
libs I use do it. But not me, no thanks. 

With the new CPU's (from e.g. intel) unless you are among the best 10
assembler coders in the world, you want have a chance of writing assembler
half as good as your compiler anyway.

If you're a command-line user (that is, someone who knows how to read and
type, rather than a 2-year-old who knows only how to point), Linux is potent, 
flexible and totally accessible. And if you must point, Linux offers X-windows.
