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

[Tispower]

I know a lot of people said it is a failure because it make little/no money. But wasn't that the whole point of the original xBox, to lose money, but to help it's successor. If the xBox had only sold say 10mil, how many sale do you think the 360 would have lost? Fact of the matter is, Sony has a userbase of 20mil for when PSP2 comes out. Also in reagrdto piracy, I know no one personally who uses pirated games for either their PSP or DS. As I've heard you can get pirtated games for your DS just as easily. Perhaps the reason I don't know anyone that does it, is becuase most of us here in the UK are law abiding :P or maybe not...
