:killer micro: [popularized by Eugene Brooks] n. A
microprocessor-based machine that infringes on mini, mainframe, or
supercomputer performance turf. Often heard in "No one will
survive the attack of the killer micros!", the battle cry of the
downsizers. Used esp. of RISC architectures.
The popularity of the phrase `attack of the killer micros' is
doubtless reinforced by the movie title "Attack Of The Killer
Tomatoes" (one of the {canonical} examples of
so-bad-it's-wonderful among hackers). This has even more flavor
now that killer micros have gone on the offensive not just
individually (in workstations) but in hordes (within massively
parallel computers).
