I'll be getting a student discount, so it's $47 instead of $59. The only reason I'm considering it is to get a replacement battery before the 2 years are up. I don't think the Apple site addresses this specifically, but I remember reading somewhere that the policy was to replace a battery that has lost 50% of its capacity (and that they're really not strict on this, so that essentially you'll get a replacement battery if you ask for it)*. Anyone know about this, or have advice? Also, can you add this later? *In a footnote on the Applecare page, it says "Service coverage is available only for the iPod and its original included accessories (excluding the carrying case) that are defective in materials or workmanship or for battery depletion of 50 percent or more from original specification.
