The advantage of SSD is two-fold-- no moving parts, therefore (theoretically) more reliability and longer drive lifespan; and ruggedizing the device in which the SSD is installed.
If your device is, say, a carputer, then SSD would be ideal: no spinning drives to crash whilst accessing files during your drive. In a laptop, I don't see much added advantage since you aren't likely to be swinging your laptop around and bouncing it off of things while working (of course, I could be wrong...).
I have been using laptops almost exclusively for a good six years now, and I haven't crashed a drive yet.
