Hi All, I was just looking at buying some RAM to update my Powerbook (1.33ghz, 1.25GB RAM), and I noticed something that I find extremely puzzling. At OWC, the cost of two 1GB memory sticks is the same price as it would cost to get 4GB for my iMac (2.66 ghz, 2GB RAM). The page for the Powerbook memory: http://eshop.macsales.com/item/Other World Computing/2700DDRS1GBA/ The page for the iMac memory: http://eshop.macsales.com/item/Other World Computing/6400DDR2S4MP/ I don't understand why the Powerbook memory costs more (per GB) than the iMac memory. Could someone help me out on this? I'm not planning on upgrading the iMac for a couple of years, but if it will be cheaper to do it now, I'll do it now. Any advice or explanations would be much appreciated!
