I am not insured as of now, but my parents plan to insure both my-and my brother's 13" 2010 MBP's. I think they were going to do something with a $500 deductible. I will have them look into this policy that you put in the first post. IMHO, it would be better to pay $45 a year with no deductible.
Oh, and I know that we have statefarm homeowners insurance.
