Apple MacBook Pro (15-inch, late-2011)
Obama also uses a 2011 MacBook Pro (15-inch) along with his iPad 3 tablet. He uses his Apple laptop for various things, such as tweeting and answering questions on Reddit. White House photographers have shown him using a variety of devices many times to carry out his presidential duties.
Air Force One: A military communications bunker in the skies
There's no way one can deny Air Force One is the most advanced jumbo-jet in the Western skies. The plane itself is designed to keep the President safe, secure, but also connected to the outside world when he's flying across the U.S. or abroad.
The Boeing 747-200B series aircraft comes with 85 onboard phones, two-way radios, satellite connections to support air-to-ground connections, secure Internet access and close to two-dozen televisions. The 4,000 square-foot aircraft has three levels, including a communications deck, in case the commander-in-chief needs to order a ground attack from the air.
But what happens in case of a nuclear attack? No trouble for the plane, which has as its core security feature the ability to repel electromagnetic pulses, and other countermeasures, such as enemy radar jamming, should the plane need to fly over hostile territories. And just because, "why not," the plane can also shoot out flares that can throw off heat-seeking missiles off course, according to reports.

Dell Latitude E6420 notebook
Despite using a MacBook Pro to carry out an Ask Me Anything (AMA) on Reddit and answering questions on the 2012 Fiscal Cliff on Twitter, Obama uses a Dell Latitude E6420 aboard Air Force One to keep in touch with what's happening on the ground. It's a relatively unremarkable Windows-powered laptop, but it's secure for classified work.
