Now that is exactly what I want to be saying in a few weeks!!! Lucky for me, my current Mini is probably superficially just as fast as the iMac will be, so i'm not suffering... its a 2011, with 16GB of Ram and a 256GB SSD.
Already dreaming about possible upgrades to this iMac in the future. Thinking about trying to find a 512GB Samsung Apple Flash from a MacBook Air or Retina ... and then rebuild the Fusion drive with that!
