I love the WaveBird. Most people bitched because there wouldn't be a rumble, but after I got used to not having to worry about my girl's 3 year old neice pulling the wires, or having to pause and lift the wires for someone to pass, plus the fact I can lay down in my bed and play my Cube, I'm hooked. I don't even remeber what the rumble felt like, and don't really care. I'd rather be able to play with my Cube way out of harm's way. And honestly, I did test my Cube, but dunno how far I got. But it doesn't really matter. Nintendo makes it, and they made it with plenty of working distance in mind. And without IR, it's a dream. I've got 3, going for 4.
