Should the PSP be viewed as a succes or a failure?

Well,any system,when compared to DS sales,could be viewed as a failure...personally,and unlike many,I never thought the PSP would come and destroy Nintendo´s dominance in the handheld market...and because of that,I view the PSP as a successful system on its own,what other handheld managed to stay in the game this long and still post very respectable sales numbers for a non Nintendo handheld?

But no other handheld had th financial backing of a company like Sony or a brand like PS which resonated so strongly with both consumers and developers. I don't think PSP outperforming the WonderSwan or the Atari Lynx should come as a surprise.
