uhmm.... I think there IS one!
But honestly speaking, I made an honest judgement between the handhelds.
The PSP has the market in games and graphics, and right now the touch screen isn't enough to give stiff competition. Right now, I think the REAL competition will be PSP vs. the New Gameboy coming out.
But my answer was in no way bias. I've experienced both DS and PSP and the truth is PSP is a superior machine in graphics and games. The DS has battery life and loading time on it's side... as is the case with many Nintendo handhelds.
Dan asked for what we thought was a better machine and what we'd suggest. So I suggested the PSP because I believe it IS a better machine then the DS in more ways then some. It's not completely better then the DS. But Dan asked and I answered, along with any others to come.
Please don't try to make this a fanboy derived thread.
