Hi, I would like to upgrade the RAM in my iBook (14", 1.33GHz) and came across some conflicting information. On the Crucial website (http://www.crucial.com/store/listmodel.asp?cat=RAM&mfr=Apple&productline=iBook&submit=Go) the recommended product is PC2700. On the Low End Mac site there is a warning about using PC2700 (http://lowendmac.com/ibooks/14-133.html). The LEMac people say that only PC2100 should be used, because there is 256MB of PC2100 soldered to the main board of the iBook. Has anyone here used PC2700 instead of the recommended PC2100 in their iBooks? Since I can't find any PC2100 at Crucial, is there another supplier? thanks! James
