  • Warren Buffett sticks to business, avoids politics in letter

Billionaire investor Warren Buffett reiterated his rosy long-term outlook for the U.S. economy and his distaste for high Wall Street fees in his annual letter to Berkshire Hathaway shareholders that always draws a big audience.

The letter released Saturday also describes the performance of the more than 90 companies that Berkshire owns. But aside from that, Buffett largely emphasized points he’s made in the past.

Buffett will likely address other topics during a three-hour television appearance Monday on CNBC, but he still may leave some people wanting more.

Here are some highlights of what Berkshire’s 86-year-old chairman and CEO did say, and some of the top things investors wish he had addressed:

While reiterating his long-term outlook for a prosperous America, Buffett mostly steered clear of politics this year.

“I’ll repeat what I’ve both said in the past and expect to say in future years: Babies born in America today are the luckiest crop in history,” wrote Buffett, who has said he thinks the economy will be OK under President Donald Trump. Buffett is a longtime Democrat who supported Hillary Clinton in last year’s campaign.

Without mentioning Trump’s immigration policies, Buffett did note that “a tide of talented and ambitious immigrants” played a significant role in the country’s prosperity.

  • Samsung delays its new phone, and showcases tablets instead

​Samsung’s product showcase Sunday is notable for what’s missing: a new flagship phone.

Instead, Samsung is spotlighting new Android and Windows tablets after delaying the Galaxy S8 smartphone — an indirect casualty of the unprecedented September recall of the fire-prone Note 7 phone . The new tablets will carry the Galaxy brand and come with many of the Note 7’s features, including the S Pen stylus and screens with rich colors.

Consumers will have to wait at least a few weeks longer for details on Samsung’s next major smartphone. That’s partly so that Samsung wouldn’t have to share the stage with its smartphone rivals at the Mobile World Congress trade show, which begins Monday in Barcelona, Spain. The delay also gives Samsung more time to make sure it has done everything right, given that any minor bug will surely draw outsized attention.

“The microscope is going to be firmly on Samsung,” said Geoff Blaber, an analyst with the research firm CCS Insight.

Samsung said the new tablets will go through extensive safety checks put in place after dozens of Note 7 phone overheated and in some cases exploded. Those incidents prompted aviation authorities to ban them on flights; Samsung eventually killed the product.

  • New LG phone influenced by Samsung’s Note 7 troubles

Samsung’s fiasco with its fire-prone Note 7 phone has pushed its rival LG to take additional precautions with its next smartphone.

Samsung recalled millions of Note 7 phonesafter dozens overheated and caught on fire . Samsung blamed numerous problems with its batteries and announced tighter quality controls and more rigorous testing.

LG said it’s doubling the separation between the battery’s positive and negative chambers to reduce the risk of a short. Samsung’s investigators found that overly thin separators were partly to blame for the Note 7 problems.

LG also redesigned the phone’s interior to separate the two main sources of heat — the main processor and the display driver — and turned other components into heat sinks to dissipate heat.

“We started by placing these two (sources) as far apart as possible and then built the phone around it,” LG spokesman Frank Lee said.

Even though the company hasn’t had the types of failures that Samsung experienced with the Note 7 batteries, Lee said wireless carriers are seeking greater safety assurances for all phones they sell.

“What’s important for them is to make sure that they present to their subscribers a quality, stable product,” Lee said in an interview. “This caught the entire market off-guard.”

  • Appealing to millennials, Las Vegas gets e-sports arena

The arena has all the features that a professional sports venue needs: stands, warm-up areas for teams, massive screens for spectators and a broadcast platform for commentators. But what distinguishes this new Las Vegas arena is its dozens of video game consoles.

The 15,000-square-foot e-sports venue slated to open Friday will host competitive video game tournaments. It’s part of a trend that the casino industry hopes will attract the millennial crowd, the 15- to 34-year-olds who are becoming majority spenders in today’s economy but aren’t necessarily interested in traditional gambling.

“Las Vegas needs to consistently reinvent itself to remain relevant to the up-and-coming generation,” said Seth Schorr, CEO of Fifth Street Gaming and a member of the board of directors of Millennial Esports, the company behind the arena. “We’ve always come up with ways to maintain our position as the entertainment capital of the world.”

Athletes participating in a tournament at the arena will emerge from a tunnel surrounded by roaring crowds in the stands. They will then go on a podium and sit at stations equipped with game consoles, monitors and other equipment.

The venue will open its doors March 3 with a three-day, $50,000-prize-pool Halo World Championship qualifier and host an EA Sports-sanctioned Madden 17 NFL tournament later in March.
