Just to make sure there's no mis-impression:
	a) R6000s do not contribute to sales of Prestone or any other
	coolant; they are air-cooled, and they are VLSI ECL, not
	massive boards full of ECL gate arrays.
	b) However, as I've said before, no one is likely to build desktops
	from these things: even if aircooled, they are hot, and a desktop
	would turn into new kind of product: above-the-desk, as it floats
	on its fans. So please stop talking about R6000-based desktops.
	c) However, it is perfectly predictable that there will be
	CMOS-based desktops with the same CPU performance, within a few
	years.  Whether you call these PCs or workstations doesn't matter much.
