Here's my two cents.

PSP pro's: the screen will have godly resolution for a system that small, sleak design,the mini-analog stick will make playing 3D games on such a small scale manageable, with Sony backing it it will have large software support, experience of home console gaming on the go, ability to play movies on the go, wireless support(almost same tech as the DS's I'm pretty sure).

PSP con's: awesome screen is too vulnerable to nicks and scratches, Sony is famous for poor durability, limited battery life kills the point of it being a handheld with some games and definately with some movies, while the library will no doubt be sizable within a year it will be filled largely with console ports, and experience of home console gaming on the go.

DS pro's: clamshell design protects the dual screens, innovative dual-screen design with touchpad tech, excellent battery life, software support from key developers (while PSP will likely have more support overall, the DS has some of the best names in game design confirmed for it), Nintendo handheld durability, sleak design(though not quite as sweet looking as the PSP).

DS con's: lack of an analog stick will make playing 3D games very painful on the thumbs, will miss out on some of the bigger titles PSP will bring in, the likelihood that few to no game designers outside of Nintendo will figure out how to utilize the dual and touch screen technologies for for innovative gameplay outside of having their game menu's on the bottom touch screen.


My vote goes for the DS. I think the PSP will have more software come out for it but as is Nintendo's mantra, quality is more important than quantity. I predict that this race will be close to a dead heat. Sony fanboys may have higher numbers but even they have to respect solid gameplay and both systems should have an equal number of that regardless of the size of their respective libraries.
