which handheld

[HotPockets]

So the holiday season is fast approaching and i think i wanna look into getting one of the handhelds. Is there a general consensous on which is preferred? Originally i was leaning towards the psp but i've been reading some things that say that sony is being extremely stubborn in regards to the UMD and that the psp may go downhill because of it. The ds lite is cheaper but i'm not sure the game selection is quite as good. Any thoughts on these issues?
