So I looked on the mac refurb store today, and saw there are currently 3 different mini models listed. Upon further inspection, I found that the 1.83 C2D mini which normally retails at 599 is at 499 refurb, which is typical. The next model though is a 1.66 CD model with less ram then the first, but a superdrive. This model is listed for 649. The third model is the 2.0 C2D with the superdrive, listed at 679. My question is, why is the older model, the 1.66 Core Duo with only 512 ram and 80 gig hard drive, priced substancially more than the 1.83 C2D and just under the 2.0 C2D. If the middle model was cheaper I would definitely consider buying it right now. Any explanation as to why this is so?
