Nintendo DS Lite
I recently got a DS Lite. The only two games I have though are Brain Age 2 and Flash Focus. Both games are great with hand eye coordination and are fun to play with at first. They do get kind of boring after playing for a while. I have also played Pokemon Diamond and Pearl, the graphics are way better than the gameboy advance and sp. The battery life is pretty good. I was able to play for around five days, about a half hour each day, before the light turned red. But if you are planning on playing for an hour or more at a time, I would recommend either putting the backlight on a lower setting or keeping it plugged into the ac adapter. Overall I think it is a great product and definitley way better than any of the old gameboys.
