  Nintendo is an amazing company with an amazing history, they are a very innovative and ingenious company. But their daring innovation has cost them before with products like the Virtual Boy. The DS will feature a PDA style stylus and touch screen. It uses Memory cards and is backward compatible with other Game Boy games. The graphic capabilties are nowhere near as advanced as the PSP, the DS has graphics equivalent to that of a Nintendo 64 on any standard television.
One cool feature is the Wireless gaming feature which allows you to connect to people within 30 to 100 feet with up to 16 players. The unit is pwered by ARM7 and ARM9 processors which can process up to 60 frames per second. Will update when more details are announced.
