You'll find thee variants of the Nintendo DS out in the wild, the original DS, the DS Lite, and the DSi. The gameplay capabilities of the three consoles are virtually identical. The DS Lite is slimmer and has brighter screens than the original DS. The new DSi is even slimmer than the Lite and also has a number of new features including built-in cameras and AAC music playback. The DS's 3D graphics performance is roughly equivalent to that of the Nintendo 64 game console, and all systems have built-in stereo speakers and a microphone.
The Nintendo DSi is the latest DS model. The DSi has larger LCD screens, 3.25 inches compared to 3 inches for the DS Lite. It also comes equipped with two 640x480 VGA cameras. One sits in between the screens facing the player, and the other sits on the cover. The system is thinner than the DS Lite, but no longer has the GBA cartridge slot which means that the new portable isn't backward compatible with GBA games. The system comes with internal flash memory which allows all systems to ship with a built-in Opera Web browser, and it has an SD memory expansion slot for music and photos. Nintendo will also offer downloadable content from an online DSiWare shop.
The revamped Nintendo DS Lite is functionally identical to the original Nintendo DS, but it features design changes that improve the gaming experience and system usability. The DS Lite's LCD screen offers four different brightness levels. At maximum brightness, the Lite is five times as bright as the original DS. The Lite is thinner than the original by a third and weighs 20 percent less. New power features include longer battery life and a quicker recharge time. The Lite features the same control scheme as the original, but the buttons and D pad feel softer. You can find the DS Lite in stores for 9. The system also comes in various colors and sometimes includes a game bundle.
