Can this cause me a problem later on? I bought a 2.0 AL MacBook in Nov during my lengthy China stay. Upon my return to the US, I went to have my Air repaired under warranty and decided to get AppleCare for both. I noticed when I registered online, Apple started the 3 year warranty for my MacBook the day I registered with AppleCare and not day of purchase. This was bought at a reseller in Shenzhen. Warranty is now good until Jan. 2012 rather than Nov. 2011. Seems like I could have waited until Nov 2009 and gotten 4 years coverage?!?
