Mac OS X 10.5 Jaguar upgrade

I got the Mac OS X Jaguar upgrade for $9.95 because I recently bought a Mac Mini just before the new OS X came out. I was depressed by how long it took to install the upgrade, the extra 3.5 GB of disk space it needed, the fact that the kernel crashed overnight on the first night (some Atheros-related bogosity), and the fact that BitRocket now crashes every 5 minutes.
