Sony Ericsson announced today the W200a, a low-end Walkman phone. The phone feature set is similar to the W300i, but in a bar form-factor. The most major difference other than form-factor is that the phone lacks Bluetooth.
Also notable about this low-end Walkman phone, is that it is the first Walkman phone to lack EDGE high-speed data. The W200a will be available later this quarter, likely on Cingular Wireless.
