I was looking through the apple site and this caught my attention. Note: Prices are in Singaporean currency, so they will be higher than what many of you are accustomed to. Imac 27': Price - 2348, applecare - 288 MBA : Price - 1288 to 2088, applecare - 388 Why is the warranty on a cheaper computer more expensive? Is the MBA expected to break down more easily than an Imac? Is it ever worth it to buy applecare for a MBA?
