I didn't go with the Fusion Drive because, well, like the person above me said, I just don't trust it yet. Yeah, it's the new "hip thing", but I try as best I can to stay away from "the new hot thing" until it's been proven for a while. Yeah, people will say "Oh Apple has tested the Fusion Drive" and "Apple wouldn't put something on the market unless it was flawless". Well, I personally wasn't there when they tested it, and I haven't seen anything published, therefor I have no way of believing that they thoroughly tested the Fusion Drive concept, through every single possible scenario that any person might put the hardware through on a day to day basis. I choose not to "just simply believe that a unit's been tested and that it's fine". Who knows, everything might turn out peachy, and that would be wonderful, and I would probably opt for one in the future, but from what I've seeing now, with the SSDs filling up too fast, the small capacity, and other issues, I just don't trust it yet...
