CNET have published a review of the Sony NWZ-E438F Walkman. 'The E-Series Walkman includes a decent smattering of features, which are slightly different than those offered by the Nano--it's a matter of personal preference which you find more suitable. The E-Series supports MP3, WMA, unprotected AAC, and LPCM (lossless) audio, and has Rhapsody DNA, so you can transfer Rhapsody Channels and other subscription content. The device also plays photos (JPEG) and video (MPEG-4, H.264/AVC, and WMV), though the latter often requires conversion for the screen, a 262K color TFT number with a 240x320 resolution (QVGA). The player supports videos purchased and rented from Amazon Video On Demand, as well. When you get sick of digital, you can tune into the integrated FM radio, which offers an autoscan function and 30 preset slots. Notably absent from this Walkman is any support for podcasts.'
