PSP or Nintendo DS

Hello! I can't really tell you what to buy, I don't know what your kids like. It really depends on them, and whether they like those games on PSP or DS, I can't say anything. But what I can, is to show you the differences between them. In my opinion PSP is better, it's from a famous brand Sony, although Nintendo is famous too, but not as good as Sony is. PSP has 133 Mhz CPU DP has 67 + 33 Mhz CPU You can view the differences between them at these websites. http://en.wikipedia.org/wiki/Nintendo_DS http://www.us.playstation.com/PSP/About http://en.wikipedia.org/wiki/PlayStation_Portable
