There is the straw man again. If you are creating a completely client side app and you find it's better to have some work done on the server side... why not use mature existing server side technology along with client side technologies. It's not a one or the other scenario.
Why work hard to move client-side technologies to the server? javascript is not so good that I want it on the server-side. And server-side lanaguages are not hard to learn or hard to find people that know how to use them.
