If you're 12 & below, get a DS lite. It's fun games for Mario etc. If you want multimedia capabilities, browsing Internet, GPS, camera, TV tuner, good graphics game, mature games etc go for PSP(it's almost as powerful as the PS2 or so I heard). I would buy DS lite for my kids and PSP for myself. Not to dish the DS, I feel PSP offer more "values" with their price range now. The core set is only about >+RM100~200 about more expensive then the DS. During launch PSP was expensive as hell!! now with Slim version and they very competitive price. The thing that ACE IT for me is the maturity of the homebrew scene for the PSP & market of the "ahem" games. I support originals and do have those GB, GB advance but now migrated to PSP. If those don't convince you, Crisis Core, Metal Gear, Jeane D'Arc, GTA etc hopefully will. As I said, it's a matter of preference....Mario vs the Rest....I love Mario, currently playing N64 emulator version in PSP. That says a lot...
