Structured data and tools that operate on that structure. Maybe steal a thing or two from LISP machines. I remember the one time I had to work on an AS/400 (iirc) how interesting it was that one of the fundamental building blocks were records instead of dumb files. PowerShell has interesting ideas too, but it'd need to be far more built-in and integrated to the OS to truly shine.
