Pando, great reply, that was what I needed to hear.

Linux, if I even suggested that they go to 11g right now, I would be dragged out and shot. We are still recovering from the upgrade from 9.2.0.3 to 10.2.0.3. We were held back by our Unix Ops people, who took the last three years planning and executing their Solaris upgrade from V8 to V10. (10.2 is not supported on Solaris 8). So now we are trying to catch up.

I have read that 11g RMAN compression is superior to 10g, so it may be in our future sooner not later. BTW, the file size limit on our Solaris boxes appears to be 64G, which is just fine with me.
