Funny, though: St. Reagan cited the same quote.

Alexander Graham Bell said it first.
He showed president elect Hayes his first generation phone which was ugly and strange looking. Hayes said the line ‘It’s a great invention but who would ever want to use one?”. Since Hayes was not president .. no WH reporter ... and no personal record.
Bell redesigned the phone to the crank phone with the ear piece on the end of a wire. Bell requested that it be installed in the WH and Hayes went for the PR op. Bell had repeated the Hayes line until Hayes allowed Bell to install the phone in the WH.
Reagan repeated this story in a speech in 1985. Obama used the same Reagan story as he often uses former Reagan stories so republicans can’t whine about it.
