This question is about those of you replaced your Macbook air 2010 because you had display, keyboard or w/e issues... If you own a MBA with 4GB ram and have issues, will apple replace it at the store without any hassles? Most of apple stores only carry 2GB at the moment, and yes, I know some carry 4GB model. But, mine is probably rare one. It is not ultimate model. It has 1.86 ghz/128 GB/4GB ram. Do you think apple will replace it at the store? Has anyone own this laptop with these specs and replaced it apple store? Please share your experience.
