WiFi is now an official word (not that anyone was waiting for this designation to use it). It is included in the new edition of the Merriam-Webster Collegiate Dictionary. Frank Hanzlik, managing director of the Wi-Fi Alliance, said, "You know you've truly made it when you're in Webster's dictionary. Webster's is a highly respected source for word definitions, so appearing in the dictionary lends real credibility to everything the Wi-Fi Alliance has been working toward." Story
