JK Shin, president of Samsung's mobile communications business, unveils the Galaxy S II smartphone at Mobile World Congress. The phone has a dual-core processor, a quad-core graphics processor, a 4.3 AMOLED screen, and a thickness of 8.49mm.
Samsung pioneered the Android tablet market with a 7-inch model that would fit in a jacket pocket. The Galaxy Tab 10.1, though, is closer to the size of Apple's iPad, which dominates the tablet market.
"Leave your wallet at home," Samsung says by way of touting the Galaxy S II's near-field communication (NFC) processor. NFC lets a phone communicate with payment terminals in stores, public transit systems, tickets for shows, and advertising--at least that's the vision. For now, until there are pay stations in use, you'd better bring your wallet with you.
