An interesting quote from the Hewlett-Packard Journal, near the end of
an article on the ThinkJet printer:

	Inquisitive readers owning an HP 2225 Printer may also
	wonder why we use the "funny" screw heads that are making
	it difficult for you to disassemble your printer.  The
	screw drive system was chosen to minimize the strain on
	operators who do the same action for eight hours a day.
	In this case, Torx[TM] drive heads have been found to
	minimize the possibility of repetitive motion injuries
	and operator fatigue.

Ink-Jet Printer Family", HPJ May 1985.
