I've just ordered a 2.3 i7 MM with 4GB RAM. I'm planning on upping that to 8GB, and was wandering whether I could use the 4GB in a 2011 MM. My Dad got the bog standard one last year which only came with 2GB and was thinking of giving him the spares. He doesn't use very often so there's no point buying some.
