Hi There, I'm new to the world of OS X and I simple can't resist the MacBook Air any longer. I realize that Apple is expected to announce a new MBA sometime around June but I currently need a small and portable computer. I'm wondering if I'll be able to get some of my money back in the event that I buy the 2012 MacBook Air and the 2013 model is irresistible (read: retina display). From what I understand Apple products tend to retain their resale value. Does any body have any figures about the price drops from previous years? I expect the value of the 2012 model to go down when the new one is announced, but by how much? Is the MBA like an iPhone or iPad where the previous generation immediately feels sluggish with upgrades to the operating system? Thanks for your input.
