It seems Samsung has taken a page out of Apple’s book with this having similar properties to the iPod Touch. These players have all the properties of a high-end smartphone minus the ability to make a call. However, they do have Wi-Fi connectivity and one can use it to access the Android Market to download their favorite apps or games. Apart from the really good capabilities of these players, the 5-inch model features a 2500mAh battery while the 4-inch model has a 1200mAh battery. Both players use 1GHz Samsung Hummingbird SoCs running Android 2.3.5. The two modem-less players primarily differ in displays and dimensions, otherwise they seem pretty similar at a high level.
