That Apple commercial showing Santa asking the iPhone's Siri for guidance? — not far off the mark. A new study shows 75 percent of cellphone users around the globe use their phones for text messaging, in wealthy countries as well as poor ones.

"Texting is widespread in both wealthy nations and the developing world. In fact, it is most common among cell phone owners in two of the poorest nations surveyed: Indonesia and Kenya," among 96 percent and 89 percent, respectively, according to a report from Pew Research Center’s Global Attitudes Project.

"In Western Europe, seven in 10 or more say they send text messages on their cell phones, with the notable exception of Germany, where just 56 percent regularly text," Pew said. "Only in India and Pakistan do less than half (49 percent and 44 percent, respectively) of cell phone owners text."

The cellphone as camera is also popular, with a median of 50 percent of those in the 21 countries polled saying they use their phones to snap photos or take videos (72 percent do in Japan, 61 percent in Mexico and 57 percent in the United States).

About 23 percent of worldwide cellphone users get to the Internet via their phones; but more than four in 10 do so in places like Israel (47 percent), Japan (47 percent) and the United States (43 percent).

Facebook, Twitter and other social networking via cellphone is also a growing phenomenon. In 15 countries, at least 25 percent said they use social networking sites. Topping the list is Israel (53 percent) and the U.S. (50 percent).

"Social networking is generally more common in higher income nations; however, this is largely driven by the fact that wealthier countries have higher rates of internet access," Pew said. "People in lower income nations who have online access use social networking at rates that are as high, or higher, than those found in affluent countries."

Two "notable" exceptions: Egypt and Russia, countries "where the role of social media in recent political upheaval has been the subject of considerable attention. In both nations, usage has increased by ten percentage points over the past year, from 18 percent in 2010 to 28 percent in 2011 in Egypt and from 33 percent to 43 percent in Russia."

The survey by the Pew Research Center’s Global Attitudes Project of more than 23,000 people around the world was conducted March 21 to May 15.

Also worth noting: While social networking via cellphone "varies considerably by age in almost all countries surveyed," in 13 of the 21 countries majorities of those under 30 use social networking sites, said Pew. The only country in which "even a quarter of those 50 or older engages in social networking"? The United States.

Updated at 4 p.m. ET: The government's transportation safety experts recommended Tuesday to ban all American drivers from using portable electronic devices — including cellphones, even if you use a hands-free device.

The recommendation, which isn't binding but which is likely to influence the decisions of Congress and state legislatures in writing  new safety laws, makes only two exceptions: You could still use GPS navigation devices, and you could use your cellphone in an emergency.

"No call, no text, no update, is worth a human life," Deborah Hersman, chairwoman of the National Transportation Safety Board, said at a news conference in Washington.

Besides calling for government action, the NTSB also urged consumer electronics manufacturers to figure out a way to "disable the functions of portable electronic devices within reach of the driver when a vehicle is in motion" while at the same time being able to turn themselves  back on in an emergency.

Jason Oxman, a senior vice president of the Consumer Electronics Association, said that as far as he knew, "nothing that would meet all of those parameters would exist today."

In general, Oxman  told msnbc.com, the focus should be on drivers' choices, not on "specific devices." He endorsed the NTSB's recommendations to the extent that they would regulate activities that take the driver's eyes off the road — “manual texting while driving, for example, you shouldn't be allowed to do it," he said. But he criticized the safety board's suggestion to disallow hands-free devices like Bluetooth earpieces.

"It may be that NTSB, in searching for a solution, is not aware of all of the technologies that exist today, and that is one reason we look forward to the opportunity to work with them," he said.

Safety advocates have long called for such a ban like the one the NTSB proposed Tuesday to reduce the phenomenon of distracted driving, which the National Highway Traffic Safety Administration says killed 3,092 people in 2010.

The NHTSA reported last week that about 20 percent of all drivers and 50 percent of drivers 21 to 24 years old admit to having texted while driving. Overall, more than three-quarters of drivers say they are willing to answer calls on all, most or some trips.

"People continue to make bad decisions about driving distracted — but what's clear from all of the information we have is that driver distraction continues to be a major problem," NHTSA Administrator David Strickland said last week in reporting the numbers. 

Scientists strongly endorse NTSB proposal

But similar studies linking cellphone use to poor driving have been challenged, most recently by researchers at Wayne State University in Detroit, who concluded last month that some earlier studies were seriously flawed.

The report, published in the journal Epidemiology, examined to earlier studies that examined crashes in which cellphone records showed that the driver had used a cellphone. Those studies "likely overestimated the relative risk for cellphone conversations," the researchers said, because they improperly assumed that the drivers were actually in motion when they were on the phone — in other words, they didn't factor in such so-called part-time driving.

Abstract: Cell Phone Use and Crash Risk: Evidence for Positive Bias

Only 10 states ban handheld devices right now, and 35 ban texting while driving.

The recommendation comes following the NTSB's investigation of an August 2010 accident in Gray Summit, Mo., involving a pickup truck, two school buses and several other vehicles.

The accident was blamed on the 19-year-old driver of the pickup, who sent or received 11 texts in the 11 minutes before the pileup, which killed two people and injured 38 others.

"That finding raises a red flag to all of us on the highways," Hersman said.

The NTSB recommendation wouldn't cover GPS devices, but — if it eventually becomes law — it would ban using your phone for any reason, even with a Bluetooth headset or speakers. The only exception would be to call 911 in an emergency.
