Sony's NWZ-A810 and NWZ-S610 now really, really official and ATRAC free

So long ATRAC, hello NWZ-A810 and NWZ-S610 Sony Walkmans. The A810 we've seen before, twice in fact, but this is the first time the S610 (pictured) has wiggled free from the rumor mill all dolled-up in full specs and pricing. The S610 series packs the same QVGA resolution in a slightly smaller 1.8-inch display and still one-ups the A810 with an FM tuner bunged inside. Both support USB Mass Storage file transfer, AVC (H.264/AVC) and MPEG-4 encoded video, and AAC, MP3 and DRM'd WMA audio formats without bothering us with any of that icky ATRAC stuff or their much maligned SonicStage software. Sony's also making nice by bringing their B100 series of Walkman DAPs to town in 1GB ($60) and 2GB ($80) models. The S610 series starts at $120 for 2GB on up to $210 for the 8GB compared to a $140 to $230 range for the same capacity A810 models. All available in September, pre-sales now.
