I just purchased one refurbished for $400, received it today and updated to Yosemite. It was such an enjoyable experience especially considering my recent switch from an Android (Note 4) to the 6+. I have always wanted to use an Apple computer but could never justify the price of a new one. After only a few hours of use I decided that the only thing I'll be using my Windows laptop for is gaming. I can't believe it took me so long but I'm glad I made the switch!
