Why can't 360 and PS3 be as reliable as the Wii?

I've sent my Wii in twice for repairs, bought it at launch. My PS3 has yet to bust or have something go wrong with it and it's an 80 gig with BC. Maybe I've just been lucky with my PS3(or maybe because it's not a launch console) or it's because my Wii was a launch console.
