The portable cassette players once nearly universally identified as the Walkman may have seen better days, but their spirit is still alive, so far as Sony is concerned. The company is apparently set to release the latest entry in the line, the slick-looking NWZA865B, a 16GB portable media player with wireless file sharing and music streaming capabilities. CNET points out that the device likely won't have built-in WiFi, due to evidence from the FCC, which does seem to limit the aforementioned streaming options. The 16GB model is also likely one of a number of capacities to be offered, ranging from 8GB to 64GB. The device is available for viewing on UK retailer Play.com with a £150 ($246) price tag and a July 31st release date.
