(Reuters) - Warren Buffett on Thursday said he could not predict the success of Apple (NASDAQ:AAPL) Inc's new suite of services but was confident the public would benefit as content providers vie for their wallets.
The billionaire chairman of Berkshire Hathaway (NYSE:BRKa) Inc, which owns big stakes in the four largest U.S. airlines, also said that industry would weather fears about safety even after Boeing (NYSE:BA) Co's 737 MAX planes were pulled from service.
He also said the pace of growth in the U.S. economy, which expanded at a 2.2 percent annualised rate in last year's fourth quarter, appeared to have slowed down, but "that doesn't change anything we do" at Berkshire.
"You really want to bet on America," said Buffett, who was speaking in Grapevine, Texas at an event broadcast by CNBC.
Apple on Monday announced an ambitious plan to reorient itself as an entertainment and financial services company, including a plunge into video streaming and the launch of a Goldman Sachs-branded credit card.
Buffett, whose company owned $40.3 billion (£30.9 billion) of Apple stock at year end, said the iPhone maker "can afford a mistake or two" as companies such as Amazon.com Inc (NASDAQ:AMZN), Netflix Inc (NASDAQ:NFLX) and Walt Disney (NYSE:DIS) Co compete for customer attention.
"Eyeballs aren't going to double," he said. "That's not an easy game to predict, because you have very smart people with lots of resources trying to figure out how to grab another half hour of your time."
But he said a decade from now, as the delivery of entertainment content improves, "the public will be the winner."
Buffett also defended Berkshire's roughly one-tenth stakes in American Airlines Group Inc, Delta Air Lines Inc (NYSE:DAL), Southwest Airlines (NYSE:LUV) Co and United Continental Holdings Inc, despite problems with the 737 MAX.
Berkshire began amassing those stakes in 2016, surprising many investors because Buffett had viewed the sector as too competitive and capital-intensive after making an investment in USAir Group he later regretted.
"I don't think it's a suicidal business any more," he said on Thursday.
Buffett added that Boeing, which has not been a Berkshire investment, "has a lot of work to do very promptly," but that "the airline industry has been so safe."
Buffett also showed his usual humour, prompting audience laughter as he removed a flip phone from his pocket during the Apple discussion.
"Alexander Graham Bell lent it to me and I forgot to return it," said Buffett, 88, who was born eight years after the telephone inventor died.
