We don't generally allow people here to buy their own PCs and Apples
either. They get a standard build from us, all centrally managed by
LanDESK. They also get a known type of hardware; they can't just buy
what the hell they like. I have more than 800 Windows desktops to
support. If they were all different and purchased ad-hoc by
individual users, I would be in even worse hell than I am already.
Most people don't build Beowulf clusters out of ad-hoc piles of
machines from God-knows-where. Most of us buy consistent hardware,
because it's impossible to support anything else.
The Tektronix graphics terminal is slightly different, because it was
just that, a terminal, and consequently doesn't present such a headache.
