* Persistant disk is available via Amazon EBS, if you want it.
* For a given amount of RAM or disk space, Mosso is somewhere between "slightly more expensive" and "over double the price".
* Mosso's price for outgoing bandwidth is considerably higher than EC2's (although Mosso is slightly cheaper for incoming bandwidth).
All in all, I'd say that Mosso and EC2 each have strengths and weaknesses, and neither is clearly superior.
