We lost track of the YP-S5 since Samsung announced the slimmer successor to the K5 portable music player at the IFA 2007. The Samsung YEPP S5 with 4GB has actually been selling on Amazon.com for $159.99 since November.

The Samsung S5 has these cool slide-out 1,500mW stereo speakers like the K5, but it is only 14.95mm thick.
Other features of the S5 include 1.8 inch TFT LCD screen, Bluetooth, FM radio, video player, music player, games, photo viewer, and more.

LetsGoMobile reviewed the Samsung S5 recently.
More details on Amazon.com.
