hi, I recently decided to switch over from PC to MAC. I've been waiting for the new imac since early this year. it's finally going to be up for pre-order this Friday. I bought a MBA i7/8gb/256GB with apple care last week. What do you guys think regarding purchasing applecare on the imac. my friend told me that getting the applecare on MBA is a good idea since it's really hard to fix and replace part in the laptop. do you think I should get the applecare for the new imac? how much is the applecare for the new imac going to cost? thanks for your help.
