Hello, I'm considering ordering one soon. But I'm wondering about how Apple Canada is in dealing with defective hardware. What if I had ordered a 17" MBP and I get a defective battery? Are there "authorized Apple service centers" in York region to get my battery exhanged? What if I get a laptop with a defective screen? I've heard stories of MBP owners with a screen that has an overly bright light only along the bottom edge (happened with Dell laptops too). How easy is it to be fixed? Thanks.
