Sony ruled portable cassette players throughout the 1980s and '90s, but with the onset of digital music and iPods, it lost its market hold. It still uses the name Walkman for its digital music players and continues to come out with different models with unique features.
Pictured here is Sony's newest touch-screen X-Series Walkman, complete with a wireless antenna for getting onto hot spots and free music with the Slacker app. This app lets you choose from genre- and decade-based stations in the Slacker rotation. So, for now, people can tune into 1980s hits and sing along with REO Speedwagon's "Keep On Loving You."
