What are everyone's thoughts on the 256GB SSD vs 1TB Fusion drive in the iMac? Both upgrade options cost the same. In laptops, I'm always insistent on 500GB or more for your drive, but with a desktop computer like the iMac, that doesn't move from your desk, having a larger external drive plugged in is a perfectly feasible solution I would think. It's even beneficial to have file libraries on an external drive for quick and easy re-imaging with minimal copying over of libraries and such. I'm also thinking having a drive with no moving parts inside an iMac that isn't very self-serviceable is also a smart move. So, which would you go with, or which did you go with?
