To comment on your (valid and important) points:
1. Client-side validation should be done in addition to server-side validation, not instead of it. The server should never trust any data from the client. The purpose of client-side validation is report on errors closer to the cause of it. To avoid a round trip to the server with data that is going to fail. And to make the reporting of errors simpler.
2. The lowest common denominator principle of browser support makes for tedious browsing on all but that lowest browser. A better approach is to support the best level of browsing on all the browsers you support. It is easy enough to detect the browser's capabilities and use them.
