I sold my 2012 Mini to fund an Air. Returned the Air (too big, too pink). Bought a 16gb loaner Mini (Space Gray) until the retina comes out. I swear the thing runs a lot faster and smoother than my 2012 Mini. I restored from Cloud backup, not set up as new. Someone mentioned the battery has a different spec than the 2012 Mini. I wonder if there are other changes. I assume we will not see a tear down. Has anyone heard anything else?
