I have been reading through different threads about memory upgrades for the MB/MBP/iMac. I plan on getting an iMac as soon as I hear what Steve has to say. However, I want to get memory from OWC, which is the least expensive I have found so far. I am currently eyeing this bundle. When I compare it to the Micron original, the OWC branded stuff looks like it has the Micron print right on the chips. So, am I actually getting Micron RAM? If so, why is it so much cheaper than the "original" branded stuff? Is there any reason why I should avoid going the cheaper route? Also, do any of you know what exactly they mean by "Lifetime Advance Replacement Warranty"? Thanks for your thoughts, guys!
