DSi 

Nintendo's latest verion of its DS handheld system. Released in 2008 in Japan and 2009 in the rest of the world, it sports an online DSiWare shop where region-specific titles can be downloaded. It also features two 0.3MP VGA cameras, SD card slot, and built-in music player, at the cost of the GBA slot. The system is 12% slimmer, has larger screens, and is over twice as powerful as preceding DS handhelds.

I got my DSi on launch day, along with 1,000 free DSiWare points.

Though not good for photography, the DSi camera is fun for playing with friends.

You can't play Guitar Hero DS on the DSi, but it sucked anyways.

DSI stands for "Dick Suck Island". Basically referring to a girl taking a guy to any private place (which is considered to be the "island" to imply a sort of seclusion/privacy) to give him oral sex (blow job) without interruption.
