What is in a NDS Lite?
The Nintendo DS Lite is the updated version of the Nintendo DS. Functionally it is identical to its predecessor, button, switch and microphone placements being a few of the changes that were made. The largest change is the shape of the device as a whole, making it smaller, lighter, and rectangular versus the original tapered edge.
The NDS and NDS Lite can only connect to the Internet with certain games that support connection with Nintendo WFC. You need to be near a hotspot or have your own wireless network at home. The NDS and NDS Lite only supports WEP encrypted wireless connections. The NDSi also supports WPA and WPA2. It also can make a wireless connection without the support of additional software/games.
