I just surfing through the apple store, and saw a refurb'ed 11" mba (2012) with the upgraded cpu option. After doing my math, it works out to almost a 15% discount (or slightly over 10% for me, since I can purchase laptops at education pricing). I have read that apple refurbed items are virtually as good as the originals, but I would like to hear from the horse's mouth as well. For those who have had experience with apple refurbs, but good and reliable are they, compared with the originals, and what exactly can I expect? Anything I need to bear in mind? Also, any idea if they will come preloaded with mountain lion, if I can download it for free, or whether I will need to purchase a new copy separately? Thank you for sharing.
