Is the PSP considered successful for Sony?

You guys are acting as if Sony has sold no games for the system. The system so far has sold 143million software units to retail. This is for for the date ending December 31, 2007. At that point it had sold 69% of GC total software and 64% of the total N64 software. By the time the PSP stops selling it will of passed both those Nintendo systems.

I'm not sure your numbers are accurate ... Nintendo announced in 2005 that they had published 2 Billion pieces of software worldwide, if the Gamecube and N64 only had (in total) 500,000 pieces of software sold it is unlikely that they would have met that mark.

 The NES sold 500, SNES 379, N64 225, GC 208, GB/GBC 501, GBA 375, DS 331, these are all of December 31, 2007 and come from this thread and were posted by TheSource, http://www.vgchartz.com/forum/thread.php?id=23700&start=0 

The PSP numbers come directly from Sony yearly reports. 

Which (probably) means that the Source's numbers are inaccurate because, even if Nintendo was overestimating their software sales, there is no way Nintendo announced that they PUBLISHED 2 Billion units of software on less than 2 Billion total units of software sold on their systems combined.

Outside of Million sellers few games from the NES, SNES, N64, Gameboy, GBA, or even Gamecube had their sales announced (or accurately tracked) in North America and Europe ...

The fact that the PSP has half as many million selling games, with total sales at 1/4 of the Gamecube should be a (very good) indicator that its total game sales are far below the 70% you suggest.
