I know a lot of us early adopters of the redesigned 15" notebooks have been wondering why we can't use the same 8GB of RAM that the newer revisions can. I'll be relying solely on my notebook for a year to complete all of my work, so I'll be running much more RAM intensive apps more often than usual and 4GB just isn't always enough. There have been successful tests of 6GB of working RAM, but there's a roadblock in the way of us being able to have 8GB of happiness. What gives? It's a firmware problem that could be easily resolved by Apple, are they really trying to force an upgrade? Thoughts on the technical restriction to this? The new revisions use the same motherboards with exception of the removal of the Expresscard, so why aren't we able to use 8GB? Let's discuss.
