What’s the difference?

I find it’s getting harder and harder to choose a new game console these days. All the games seem to be available on every single console. So how do I choose which one I want? The technology on each console is different, I know we have the WII which is great if you want to lose weight and play active games. The PS3 has better graphics than the PS2, the PSP is small and handheld, The Nintendo DS has touch screen technology, and the Xbox has wireless technology. All these new technologies are good but it confuses me that I just want that new game. I don’t care which console it’s for.
