The PSP went off to a bad start, but the line up its got now in my opinion is better than the DS's. And the new features its going to get soon will make it a far superior handheld to the DS, im most looking forward to it being able to emulate PSX games, legally by Sony. And by the looks of it, its going to be free.
Then again, I dont really know what the DS is going to be able to do in the next year or so, I should probably research.

I play my PSP all the time, Im not surprised that alot of people arent playing it, mainly because there arent many PSP games that arent racing or action games. I only started playing my PSP more when Street Fighter Alpha 3 Max came out...
