A review of the Sony NWZ-S610 (2GB, black) Walkman MP3 player has been posted over at CNET. ‘The newest series of Walkmans comes in a variety of capacity/color combos. You can go with a 2GB ($120) S-615 version in black, pink, red, or silver; a 4GB ($160) S-616 model in the same choice of colors; or the more capacious 8GB S-618, which comes only in black and will set you back $210. It's not the cheapest player on the block--the Creative Zen V Plus, which offers roughly the same features, runs 30 to 40 bucks cheaper. However, the NWZ-S610 offers a more sophisticated design with a larger (1.8-inch) screen and a higher-quality feel. It's also a little larger overall, measuring 3.1 inches by 1.6 inches by 0.4 inch, though whether this is a good or bad thing depends on the user. It's certainly pocket-friendly.’
