He said a "good" system, not top of the line gaming rig. :P Capable of running most games on average settings. My 3.2GHz processor and 2GB ram with a crappy 128 MB video card suffices for most things and it cost me not much more than a PS3.
Also I'd be willing to bet that it's the high prices of the 360 and PS3 that caused the Wii to be $250. If the 360 and PS3 launched at $300, I guarantee the Wii would've launched at $200.
