I don't hate PSP, or Sony. I just like Nintendo more. Very few games on Sony's systems have ever appealed to me. Final Fantasy VII, Kingdom Hearts, Katamari Damacy, and Dance Dance Revolution. Katamari is coming to the DS, and the Mario Mix of DRR is coming to the GCN. Buying a system just for two games that I like doesn't seem logical too me.
The PSP is mighty impressive, but I wish for the portable market to stay seperate from the console market. I don't want a mini console, I don't want 2D games whipped out. I want something different than the consoles, and the DS's touch screen covers that, and it still feels like a GBA at the same time, so it fits my needs. Buy a system based on your preferences. I have mine, the PSP is good but I don't want or need one.
