Largely enjoyed my experience with 64-bit 13.04 from the LiveDVD - seems quite faster than 12.04's Unity! However, Firefox froze when I minimized it, then kind of tried to 'come back' after a few seconds of me waiting for it, then froze again.
Is this at all related to the fact that I was using the LiveCD/DVD/whatever it's called now? And if I can reproduce it, what do I need to relay to the correct individuals?
EDIT - I see now this is a recognized issue of Ubuntu 13.04 - #1163503 on Launchpad. Since I prefer Chromium on Ubuntu I have my workaround, and I see that since it is a bug I will not need to keep this post open. Thanks for being helpful, everyone.
