Sony has unveiled the latest update to the A-Series Walkman line with some serious features. The new NW-A840 series, available in black and brown, simply is the most brilliant Walkman offering from Sony to date – it has all of the features people have been asking for in previous Walkmans while shedding what it needed to. In my opinion, this is the most stylish appearance I’ve seen in a personal media player – and it has a jaw-dropping 2.8 inch WQVGA OLED screen. This is also the thinnest Walkman ever created at only 7.2mm. Sony has also finally come to the table with a better assortment of capacities – with the NW-A845 (16GB, Y24,000), NW-A846 (32GB, Y30,000), and NW-A847 (64GB, Y40,000) all due on October 31st. What’s also new for the first time is a TV-out function, that can output at 720×480 (SD) quality.
