The Walkman had a huge impact on the way people listen to music, so it's surely worth celebrating its anniversary. That said, most people don't have huge tape collections anymore. So Sony's 40th Anniversary Walkman is a digital affair. Officially dubbed the NW-A100TPS, it's an Android-based music player with 16GB of storage expandable via microSD, streaming support over WiFi, Bluetooth, and a 3.6-inch touchscreen. For nostalgia's sake, it arrives in packaging inspired by that of the original TPS-L2 and includes a soft case that looks like the TPS-L2 itself.
