That's a silly argument, because it simply relies on the fact that most
uses of computers aren't CPU-bound at all. In the same way I could
probably steal half the RAM from your system and clock the CPU down 50%
(the BOFH's favourite revenue-generating technique!) and from 'the
interactive performance of common applications' you wouldn't be able to
tell the difference. I don't think that _means_ very much, though.
