Well, I wouldn't sue them for like $10 million, but I'd expect them to pay the TV that is broken, if my insurance doesn't. Let me explain...
I don't have a Wii, but let's say I'd buy one. What I do have are hands that start to sweat instantly. So I have my Wii, and I play tennis. To avoid throwing the controller away, I use the wrist strap they kindly put onto the thing, which was a good idea. The bad idea was to not make it strong enough. The controller slips from my sweaty hands, the wrist breaks, and it flies into my newly bought plasma. The inusrance doesn't pay, as they say I acted negligent, and all Nintendo gives me is a new strap. So who pays for my TV?
Let's say Nintendo makes cars. I buy one, drive it normally and then total it because some little part failed. The inusrance doesn't pay for whatever reason, I have my totaled car, and all Nintendo does is replace that small part that failed, and leaves me with a totaled car?
