Wait to register Applecare?

Question

I just bought an Applecare Plan for my one month old 20" iMac Core2Duo and I'm trying to decide whether to enroll it now or wait. Here's my reason for waiting.
Let's say I enroll it now and in in 6 months I have a problem with the iMac which would require replacement of the iMac and which would be covered under the original one year warranty. In that case, my Applecare could be transferred to my replacement which would then have only 2.5 years Applecare coverage (the original 3 yr, minus the 6 months already used).
On the other hand, if I wait to enroll until anytime up to month 12, then I would still have a brand new unenrolled Applecare Plan to use on the replacement iMac, again waiting until anytime within the first year.
For the sake of this discussion, let's disregard the 90 days phone support, and just consider the actual warranty. Is there something I'm not thinking of or is this not a valid reason to wait?

The language is very straight forward, not the usual legal doubletalk associated with many warranties. (emphasis mine)
Warranty Coverage 
Apple's warranty obligations are limited to the terms set forth below: 
Apple, as defined below, warrants this Apple-branded hardware product against defects in materials and workmanship under normal use for a period of ONE (1) YEAR from the date of retail purchase by the original end-user purchaser ("Warranty Period"). If a hardware defect arises and a valid claim is received within the Warranty Period, at its option, Apple will either (1) repair the hardware defect at no charge, using new or refurbished replacement parts, or (2) exchange the product with a product that is new or which has been manufactured from new or serviceable used parts and is at least functionally equivalent to the original product, or (3) refund the purchase price of the product. Apple may request that you replace defective parts with new or refurbished user-installable parts that Apple provides in fulfillment of its warranty obligation. A replacement product or part, including a user-installable part that has been installed in accordance with instructions provided by Apple, assumes the remaining warranty of the original product or ninety (90) days from the date of replacement or repair, whichever provides longer coverage for you. When a product or part is exchanged, any replacement item becomes your property and the replaced item becomes Apple's property. Parts provided by Apple in fulfillment of its warranty obligation must be used in products for which warranty service is claimed. When a refund is given, the product for which the refund is provided must be returned to Apple and becomes Apple's property.
