Lionel Menchaca has a cool post on the Direct 2 Dell blog, about a presentation recently made by Dell. They demo a lot of cool technology and one cool demonstration is of a laptop with solid state disk vs. a normal drive. The laptops are both the same except for the hard drives. One has a 30GB solid state drive, and the other has a normal 80 GB drive. You can clearly see the faster boot times on the solid state drive.
Its a very rough comparision, not specific benchmarks but its fun to watch none the less.
