Gore Joining Board of Apple Computer By THE ASSOCIATED PRESS CUPERTINO, Calif. (AP) -- Former Vice President Al Gore was elected Wednesday to the board of Apple Computer Inc. Gore, who popularized the ``information superhighway'' as vice president and helped secure money to build the Internet as a congressman, praised chief executive Steve Jobs and other Apple executives for making the computer company ``once again the very best in the world.'' But despite critically acclaimed products and a supportive fan base, Apple only has a 3 percent share of the U.S. personal computer market, according to the research firm IDC.
