So my friend asked me what handheld system she should get for her 10 year old son. I told her that the DS would probably be a better fit since it has a large library of games, is backwards compatible, and seems more suited for a 10 year old. She was curious about the PSP because it seemed "more mature" and would be better for her son because a friend told her that her 11 year old son was more happy with his PSP than he was with a DS. Mind you, I don't either of the two systems. I'm merely going off of heresay and conjecture. I've done a little research, but testimonials are hard to come by, as compared to professional reviews. SO I turn to the more knowledgeable than I, the TFW gamers. Which system would be good for my friend to buy her 10 year old son for Christmas? Do you have any children with protable systems to draw experience from?
