well on the laptop the difference is night and day, cos the original drive was 5400rpm.
the system boots soooooo much quicker. shutdown takes literally about 2 seconds, loading programs is a lot faster (like protools)
importing audio in protools is very very fast and even loading heavy plugins is nippier..
obviously backing up sessions and stuff is a lot quicker too..
i'm not sure how much of a difference i'd see between raptors and ssds, but it's handy to be able to pull and ssd out of the machine to be portable,,without having to worry about breaking it in transit, since there are no moving parts!
also...in normal temperatures the laptop is literally silent now..so recording on it is really nice.
