Alright.
The DS: Revolutionary. Great games. More interaction. More battery life than PSP.
The PSP: Average, media player, great graphics, bad gameplay (an MGS CARD GAME? PUH-LEASE), shitty battery life, shitty framerate (Play the Wipeout game.. ech..), and as always with Sony, shitty manufacturing (Missing pixels, Games popping out of the drives, etc.)
Emulators don't count for PSP because you obtain the software illegaly. Also, they were released on older systems, which gives the PSP a whole lot of negative points for having "ported games".
Look, you are all saying that the PSP is outselling the DS, the PSP is better than the DS, etc. First off, both are based in Asia (I heard that Sony is based in Hong Kong) and I'd say they care more about whats going on there. In Japan, the DS is putting the beatdown on the PSP because of all of Nintendo's support for it which will be availible here in the US in the future.
All that matters to those companies is the battle at home. They probably hardly give a shit on how it is shaping up here. http://www.gamespot...23/news_6128046.html
