Anyone who has a PSP and a DS, I would like to know which you prefer? I have a PSP which I don't play much and am thinking of getting rid of it for a DS. Which system do you prefer? Can the DS be tied into the Wii in any way? I don't have a PS3 so linking a PSP is not an issue. I had liked the PSP for video but I have an iPhone now so I will be watching movies on that instead. If I were to keep my PSP what can be done as far as modding goes?
