Query: The PSP sucks!

The PSP is the worst. The DS is the best handheld game system ever invented. Which game system is better? The DS all the way!!! Nintendo is the best game company and has been around since the 1950s! Sony PSP is just a bad copy of all of Nintendo's work. Don't waste your money. Buy a DS and do what that one kid said, flush the PSP down the toilet and throw it in a dumpster.
