We will probably use a combination of SSDs for speed and HDDs for storage for a long time. I don't think it's cost effective to keep everything on a SSD (like: movies), as the cost/GB is ~15x higher than the HDD storage. I have a combination of SSD+HDD in both my machines (desktop: first-generation 40GB SSD + 2TB 7200rpm HDD, laptop: 128GB SSD + 500GB 7200rpm HDD) and I get the best from both worlds: cheap storage for large files on HDDs and fast OS and applications on SSDs. Because of this combination I don't feel the need to use a bigger (and costly) SSD.
