In May I ordered 16GB of memory for my ultimate iMac. I was very happy that I paid only $190. Then the memory was defective (first time in decades!), so I returned it, and placed a new order, in which the same Crucial DIMMs were $160. I was happier, though mostly because the memory wasn't causing horrible stability problems. Now those same Crucial DIMMs? $114. http://www.newegg.com/Product/Product.aspx?Item=N82E16820148345 If you instead go with Corsair, it's $110. If you want to deal with rebates, $90. http://www.newegg.com/Product/Product.aspx?Item=N82E16820145281 ----- Since 4GB SO-DIMMs have bottomed out, this means we should start to see 8GB SO-DIMMs start to be produced in greater volumes in the next few months, and hopefully the prices of those come down from $100/GB, closer to $50-60/GB. They should hopefully be closer to $15/GB in 12 months.
