PSP vs DS

[grouchie]

Guys,
I'm really considering getting a hand held system to help ease the boredom at work. I am not sure which one to get.

I noticed that the PSP is finally coming out with Final Fantasy games, and they also have a couple GTAs and the Prince of Persia that I would like.

But, other than that, do they have a good selection of titles in the genra's of games that I am already looking at?

Just not sure if spending the extra money for the PSP would be worth it over going Nintendo.
