Just purchased a mid 2012 MBA to replace my mid 2010 MacBook Pro (2.4ghz core2duo 4gb of ram). New machine has the 8gb of ram upgrade along with the 256gb ssd and 512mb intel 4000 graphics. WOW is all I can say. This machine is shocking to me. Only set me back 730 after shipping from eBay. Pretty stoked! Has AppleCare until February 1st 2016, 7 cycles on the battery, and is in literally perfect condition. I can't believe the deal I got!
Side note: how much do you recon my mid 2010 MacBook Pro is worth? Like I said its a mid 2010 pro 2.4ghz intel core2duo with 4gb of ram and the 250gb hard drive. I have the original box, restore disks, charger, and paperwork. In great shape minus a few dents on the bottom.
I would say $600.00 depending on the battery cycles. The dents though are a big deal for some people.
