Still, some security experts caution that the risks related to the presidential BlackBerry have been overblown. Although it could be dangerous for the president's location to be compromised, they also say that, most of the time, the president's whereabouts are broadcast on television.
When it's crucial for the president to be absconded to an undisclosed location, it's easy enough for the Secret Service to turn the device off.
"I think people need a little bit of perspective here. It's not like Barack Obama is inventing having important content on a BlackBerry," said Dan Kaminsky, a computer security consultant for Seattle-based IOActive, Inc., who is credited with discovering a major Internet security flaw.
For years, Research In Motion has had its devices in the hands of high-ranking executives and military leaders.
"You're talking about the one platform that has always had to assume it's under attack because of the importance of the people [who use it]," Kaminsky said. "That sort of pressure is what RIM has been living under."
As more people choose a smart phone over a regular cell phone, he acknowledged that it's true that hackers will more aggressively target devices like BlackBerries.
But building an attack that only targets one person -- even if it's the president -- isn't as worthwhile as building attack that that imperils a larger chunk of the connected population, he said.
More importantly, he emphasized, just as President Obama has unparalleled physical security, he will also have unparalleled digital security.
In addition to a "secret sauce" of encryption to keep obscure the device's messages, Kaminsky expects security engineers will work around the clock to fend off possible hackers.
And it seems that, when it comes to mobile devices, our geek in chief will be shooting from both hips.
In addition to the BlackBerry, experts expect Obama to use the Sectera Edge, a high-powered mobile communications device made by General Dynamics and approved by the National Security Agency.
"You could have a two-device scenario here," said Sascha Segan, lead analyst for mobile devices at PCMag Digital Network.
Obama could shoot off an offhand note to Malia with his BlackBerry and then pick up the Sectera to answer a call from Gen. David Petraeus, one of America's top military leaders, Segan told ABCNews.com.
The $3,350 smart phone is one of only two such devices approved by the NSA for information classified as "Top Secret," Segan said, adding that it encrypts voice conversations and classified documents to a nearly unbreakable extent using protocols beyond the reach of average citizens.
But, in some ways, Segan indicated, although it's bulkier and more rugged than the sleek BlackBerry, the Sectera is so powerful it almost renders another device unnecessary.
With a flip of a switch, the president could alternate between classified and non-classified exchanges. Theoretically, he could use the same device to communicate with Malia and Petraeus.
But aside from being the president, Obama is just another guy who wants to hold on to what's familiar.
"I've been covering wireless devices for five years ... [and] people get attached to their particular devices," Segan said. "A cell phone is a very personal thing -- an extension of themselves."
And, ultimately, he pointed out, the leader of the free world gets the final say.
"He's going to take advice from people," Segan said. "But to quote his predecessor: He's the decider."
