The once-popular Sony handheld PlayStation Portable has turned five years old today, with Sony announcing that the many revisions of the handheld have sold 60 million units worldwide.
17 million of the sales have been in the United States. In comparison, the PSP's biggest rival, the Nintendo DS/DSi has sold 125 million units globally, with 40 million in the U.S.
Dille says the latest PSP hardware revision, the Go (which removed the UMD drive) has "met our expectations," although sales have notably been low.
