Sony sells 50 million PSPs worldwide, Mario unimpressed

As of January 2009, Sony Computer Entertainment claims to have sold 50 million PSP handhelds worldwide. A number that includes all PSP-1000, 2000, and 3000 series devices sold since December 2004. That's a big number, no matter how you slice it... unless it's Nintendo wielding the perspective knife with its claim of 96.22 million DS handhelds sold between December 2004 and December 2008. Then again, PSPs have sold a bit better than Gizmondos, so there.

For a competitor of something that doninated Handheld altogether for so long, the PSP has done well.
Not saying PSP doesn't have some great games, it just needs some more like Crisis Core and GoW.
