A solid but lightweight candy bar-styled phone, the Sony Ericsson Walkman has a black exterior with a curved rubber back panel that rests lightly in the palm of the hand. The Sony Ericsson Walkman Mix is designed to be reliable and budget-friendly for music enthusiasts who want a full set of features in a phone that can also be customised. The smartphone is diminutive at 9.7 cm (3.8 inches) wide, 5.3 cm (2.1 inches) high, and 1.5 cm (0.6 inch) deep, ideal for easy carrying or for slipping into a pocket. Function buttons cover the chassis of the Sony Ericsson Walkman for ease of use, including a volume rocker switch, a power/lock-down button, a camera key, and a home menu button. The Sony Ericsson Walkman Mix features a capacitive touchscreen that offers bright images and sharp graphics while responding to the slightest fingertip touch on its glossy surface. Internet browsing is made possible on this smartphone through the integrated Wi-Fi technology, which also allows for music downloads, song recording, and more. The Sony Ericsson Walkman also features a 3.2 MP camera that offers video clip functionality as well as still images, all of which can be safely stored with music files in the 32 GB-capacity microSD memory card slot.
