I'm new to the Mac world. I joined MacRumors after reading many helpful and insightful threads. I purchased a MacBook Air not too long ago without being informed that there is a highly awaited update to be released, rumored to carry specs such as an i5 processor, 4GB DDR3, 256SSD, and a much longer battery life, (40% increase). I love the MacBook Air; I bought the highest specs for the Rev. 2 hoping it would last me a long time. I carry it to school, and wherever I go. I was simply wondering if Apple does a program where you can send your current MacBook into them, and have your specs refreshed and paying a fee for such services. I've also thought about selling my MacBook Air on ebay/craigslist, and then pay the remaining difference for the newer MBA. I was wondering if anyone could give me any insight on how to approach this, as I'm new to Macs. What do most of you Mac users do in times of an update of hardware?
