Going to watch the video now but first want to comment that as a staunch Nintendo fan and vocal PlayStation dissenter, I felt that the psp go was a more enjoyable system. Obviously ds had its strengths in terms of price, game cards, bigger library, and Mario Zelda. But the ds was not a sexy device and its capabilities were n64-ish. PSP go had open worlds with ps2-ish graphics. Battery was big and storage was adequate for a good six games installed. As a GTA fan, psp go was easily more rewarding to keep in my pocket. It was a lot less dorky to pull out and show off for sure.
I never owned a regular psp. It was cool though.
