Personally went with the 1Tb Fusion as it seemed the best compromise Price/Performance..
Would have liked the 1Tb SSD instead but did notmake financial sense, figure it will last longer than the 1Tb Fusion, but will consider upgrading if/when the 1Tb Fusion pops its clogs.
If money is no object then SSD all the way, at the moment for me the Fusion was the sensible choice, will be different for everyone, although I think the base HDD is the least preferable option for almost everyone!
