Well, most of my colleagues and customers with desktop systems have rather extreme storage requirements. Individual files multi gigabyte composited image files. So an SSD is nice for speed, but cost prohibitive for everything to be stored on SSD. What they need is a file system that puts hot files on the SSD and cold files on HDD. I think there is btrfs code being worked on to do just that. I don't know if it's any more or less difficult to do this on other filesystems.
