I just put State Farm insurance on my MacBook Pro. It cost something like $2.81/month. I'm going back there next week to put coverage on me and my dads iPhone 4's and on my iPad. It's kind of stupid not to do it being as it is so cheap. My agent told me adding those 3 items will only add like $1.50/month.
In review: AppleCare + State Farm = A lot less worrying.
