(topic) And i like them both the same. Both have good features and bad. The psp(once you download the new firmwear) has free internet, and is graphicly more powerfull. The bad thing is it is more expensive and the battery life is bad. The DS has really fun games and the touch pad is very fun to use.  The bad thing about the DS is, well.......... kiddy games? To conclude i like both the same. 

Things you should get for your psp to make a better experience

1. 1GB memory stick($50bucks but can hold 500songs!)

2 30MB memory stick(great for game saves only)

3 Socom fire team bravo and Daxter(two great games!)

Get those things and you'll have a great time with your psp.(it even rivals the DS with those!)
