I got my 2.5 Ghz Rev 3 MBP , Extra ram and case insured through State Farm's personal articles insurance.
Although the guys at a local office quoted me at 33 dollars for the entire year, I get a letter in the mail from corporate saying I owe them 22 dollars extra within the next couple of days or my entire policy is null.
Not that thats a big deal, I just wonder what kinda of hassle I'll have to go through if I need to file a claim....
Total coverage amount is about $2800.
Then again, what you may be referring to is not really insurance but warrenty, and I think there is a specific clause for wear and tear in my policy. Oh well. By that time it will have founds its way to a river somewhere (jk) (?)
