For those that haven't yet gone down the iFaithful portable media player route, there's always the Walkman. Sony officially unveiled updates to its A, S and E series line of players just last month, and now plans to dole out a free trial of Music Unlimited to owners of the NWZ-A860, S760BT and E460 when they go on sale this September. The streaming service, formerly known as Qriocity, brings with it a catalog of over 10 million songs and will be available gratis for 180 days, after which it'll run you $3.99/mo for basic service and $9.99/mo for the premium offering. It might be too late in the game for the company to wrestle back the portable audio crown but, hey, you can't fault it for trying to sweeten the MP3-playing pot. Official PR awaits you after the break.
