Os/2 has the same priority boost for interactivity. You can't really do that in bash, as a non-root bash can't raise its priority above normal. (If it could, all sorts of programs would do that in order to look like top performers.)
I believe you can get this effect today by starting all processes with a slightly lower priority (use nice), except for bash and X at normal.
You might get a more NT-like effect by modifying the keyboard driver to raise the priority of whatever process receives keystrokes, but that will help the console only. A telnet/ssh user wouldn't benefit.
