Even better in a personal workstation: you will be able to work in
silence wherever you are (remark: somebody on this group said that
the disk drive was noisy; don't worry, you can anihilate this noise)
... Or, if somebody is disturbing you by talking all the time, you
could turn your nihilizer on, and no sound would come out of his
mouth!
