'Zen Touch vs NW-HD1 vs 4th Gen iPod iPod PROS: -Good support from Apple forums -Abundance of aftermarket accessories -Small dimensions and light weight -iTunes music management software easy to use -FireWire port. '
'Genius feature creates on-the-go playlists around a single song.'
'Rather, the Touch includes a backside illumination sensor, which is designed to make the rear-facing camera perform better in low-light.'
'Its indoor video quality is poor, and without even basic controls for brightness and contrast, there's nothing you can do to compensate for bad lighting.'
'Slim design with larger screen.'
'The bundled headphones do a capable job of rendering FM-quality broadcasts but fall a little flat when it comes to high-quality audio files, and still struggle with sounds at either extremes -- rolling, deep bass or high trebles came out a little squidgy for our tastes.'
'I plugged several pairs of headphones into the new nano and I was as pleased as ever with the sound, playing MP3, AAC, and AIFF files.'
'The FM radio and JPEG photo viewer found on the NWZ-S710F are nothing special, but both are easy to use and add value to the device.'
'In PC World Test Center audio tests, it netted a signal-to-noise ratio score of 82 decibels--just a shade below the latest iPods and the top-ranked Creative Zen X-Fi --as well as a barely registering harmonic distortion and noise level of 0.01 percent. '
'Even without any of the whiz-bang options or noise-cancelling activated, music is full-bodied and vibrant. '
