What are the exact differences between the Nintendo Gamecube and Panasonic Q

Actually the only version being produced is the slim version ... you won't find a new -fat- version anymore... (unless someone sells them like diamonds). Anyways. The difference among the new models (slim ones) is based in their hard drive size. The actual versions are 120Gb and 250Gb ... but beware, this month Sony Japan will release new Slim versions in white color with higher high drives ... !!!

The main difference is that the whole game is flipped, horizontally. In the Game Cube version, Link is left handed (as he was in all previous games). In the Wii version, he is right handed. In order to avoid re-doing all of the graphics in the game, they just flipped the entire game - Lake Hylia is in the southeast corner instead of the southwest corner, if there is a path to the left in the Game Cube version, it is to the right on the Wii, etc.

I recall that Nintendo stated that this had something to do with players using the Wiimote in their right hand, and the interaction with the game was odd if Link was left handed, but I'm not positive on that.
