It’s a good point that the benefit of an SSD will depend on how many significant files don’t fit in the SSD portion of the Fusion. My initial post was a bit unqualified. I also see that they’re interested in snappiness-for-the-buck which could mean that the RAM is still the better purchase if it’s only a third as much an improvement as the $500 SSD. So it really comes down to how much of that drive is full (I’m guessing much of it if they want a 2TB SSD) and how often they load something very large into RAM or how often they have enough apps and documents going that frequently accessed swap is an issue.
