I've shown many small players receintly. Here is another from Sony.

"Sony's got all carried away and announced 4 new Network Walkmans all with the usual array of unmemorable number and letter combo names (when are manufacturers going to start calling their gadgets things like Glenda and Cedric? Maybe then I wouldn't let myself down when having my gadget credentials tested by the boys). The NW-E505 and NW-E507 Network Walkmans come with 512MB and 1GB of memory (respectively) and there are also the 512MB NW-E405 and the 1GB NW-E407. All four players support MP3s (as well as ATRAC3, ATRAC3plus, WMA, and WAV). The 500s have FM radio while the 400s (pictured) don't, but that's about the only difference really. All three have a neat quick charge feature which lets you gain three hours' of battery life for just 3 minutes spent plugged into your computer's USB port. They'll be here in April." [via shinyshiny]
