I won an mp3 player a few months ago. Its a Sony Network Walkman, model NW-E403.
This model sports 256MB of flash memory (holding 55 mp3s right now) and an incredible 35-50 hours of play on one charge! (no batteries to put in – charges via your USB port). It seems quite easy to navigate and the songs are entirely playable. I like the fact that this unit is quite small but the display is still easy to read. The requirement that you transfer your songs through the provided Sonicstage software is a bit of a drag (Windows only), but it seems to work reasonably well. You can also store files on the player as well, if you want to connect it to a PC and use it that way (but they’re not viewable in the mp3 player’s display). For the price that I got it for, it was great, of course. Now, this unit seems to buck the trend and be less expensive if bought in person. I noticed that the price online was as much as $30 higher than what the local electronics store was selling it for.
This unit also comes in 512MB, 1GB, and 2GB models. If you are intested in this neat little toy, I’d suggest that you shell out the extra $20-30 for the larger capacity.
