I can't say enough good things about this device. It was a great buy. It (a) plays MP3/WMA songs, (b) allows you to convert all of your old records, tapes & CDs to MP3 format very easily using the built in line-in encoding/recording [in other words, no PC is required to convert your files], (c) you can listen to and RECORD live FM radio like a DVR device, (d) you can drag & drop MP3 files using Windows Explorer directly to the device - as it adds a drive letter to your PC when you plug it in, (e) it has a superb battery life, (f) it has a huge storage capacity - 1 gibabyte worth of space, (g) it's teeny tiny and (h) it functions as a voice memo/recorder with it's built in microphone, (i) and there are too many more good features to list. This a MUST HAVE DEVICE for anyone who enjoys music and/or audiobooks. It's cool, sleek and very functional.
