My bad -- it appears that I saw the 16 in the 1600 MHz bus speed, for the upgraded model, and in glancing too quickly, mistook that for the size (looking again at the web page, still open in another tab). To follow up on the RAM specifications, would the chip count/size for the 16 GB model be equivalent to two 8 GB DIMM's or to one 16 GB DIMM (as they are currently constructed)? (Asking anyone who knows.) I assume the latter, representing higher per-chip density, would reflect significantly higher cost. P.S. I'm not a fan of small, light gray text on a white background (the specs listing on the Apple product page).
