Howdy all. I want to get a 1GB SODIMM for my iBook G4 that I have but was wondering..... what if the PC2700 SODIMMs are backward compatible? Would that mean that I can buy memory for my Powerbook in the future but still use it while I have my iBook? I am going to buy a Powerbook at the end of the year but I want to upgrade my iBook now. Does anybody know if this will work? I'm looking to get a 1GB PC2700 Micron chip and want to see if it will work in a PC2100 slot for the iBook. Thanks! Cheers! Mark.
