Prices at Rock Bottom for 4GB, 8GB Mac Pro Memory Modules
Mac Pro memory prices have dropped some more for 8GB modules. See Why I Always Have At Least 24GB memory (and why a 16GB iMac doesn't cut it).
Apple memory remains very expensive, for more on that topic, see my Jan 28 entry.
Prices for iMac and MacBook Pro are also very low (excepting the very latest 12GB and 16GB technology for the MacBook Pro).
