Yes and no. We use hardare loadbalancing to spread across our content servers. All connections are stateless/sessionless, so each request is atomic and requests are sent to the most available server.
On each content server (dual 1.3G PIII) we have mod_jk configured to use 2 loadbalanced "servers", each an AJP connector running on the same machine within the same JVM, but each on separate ports. Each connector then has its own processor threads. This configuration isn't in the documentation, but it gives us the best throughput.
We have migrated to Linux, Apache, and Tomcat over the last year-and-a-half. We use it both in development and in production, across 100 or so boxes. As with everything, there are issues, but for the most part we are very happy. Even most commercial vendor's idea of a "big" site doesn't come close to what we do, so we have found very little difference between problem solving in the open-source and closed-source worlds.
For what we do, you can't beat the price... And yes, that includes the price of our time.
