I went to go to the local Microcenter and went to their Mac section to purchase a stick of RAM. When I asked for a 256MB stick he told me they were out but went up front to check to see if there were any. He returned and told me they were out of the usual model he sells but told me any 144pin SODIMM should work. I was skeptical since I heard ibooks only take a certain type of memory stick. So my question is are all 144 pin SODIMMs the same? Have I been duped into thinking there is a special SODIMM to only pay for the markup price of being an ibook? If all of the 144 pin SODIMMs are the same then I might as well go to my local Best Buy where they run specials of notebook memory sticks all the time.
