Yes, but if you bundle them (the validation functions) up in a .js file
you can include it everywhere and rely on the browser caching it. Speed
is relative. Yes, your server-side validates are fast, but what if you
had 500 users? 5,000? 50,000? And even if your power-server could handle
it, could your connection to the net? 

FWIW, could you also validate all the fields at once? It's somewhat
annoying to have 3 errors on a page, be told about the first, fix the
first, then be told about the second, then fix the second, then be told
about the third...
