I just ordered one of the new 15" PowerBooks with the standard 512MB of RAM. I want to upgrade to 2GB myself after I receive the PB. NewEgg is currently selling these Kingston ValueRAM 1GB sticks (DDR2 PC2 4200 SODIMM). http://www.newegg.com/Product/Product.asp?Item=N82E16820144183 Based on the specs I can find on Apple's site, that RAM should work? Any thoughts.
