I'll never understand people who are sticklers for 'correctly' using some corporation's trademarks. "Can you xerox a copy of that for me?""You know, our photocopy machine is made by HP and the Xerox corporation doesn't like when people genericize their..." Why the hell do they care on the corporations behalf? If you aren't being paid by that corp to care.. then why?
"xerox" is a pretty common term for photocopy (particularly in Asia), just as "google" is a pretty common term for looking something up on the internet.
I'm not talking about people who are unfamiliar with the term xerox, meaning 'photocopy' (which has been in use this way for decades.) I'm talking about people who object to the use of this term because the Xerox company hates it (they could in principle lose their trademark because of it, but that's not my problem.)
