Companies with best service plans for Nook Color eReaders?

Almost all service protection plans are extremely overpriced. Remember, you're buying insurance, which is all about probabilities and payoffs. Paying $50 (B&N charges $54.95) for a $250 product (that rapidly becomes obsolete) is placing a bet that it's more than 20% likely that you'll need to use the policy. The actually likelihood is probably less than 2%, so such plans are simply too overpriced.
