Another thing about the wavebird is the price. Compare it to Logitech's equivalent. Not only is it alot cheaper, but it is a lot more economical. I guess the Logitech wireless controller does have rumble, but I don't think it's worth it considering how much it costs, and how much battery life it eats up.
I also reckon that the wavebird is more sturdy than the original wired controller for the GC.
