Affraid to Upgrade from FC9 to FC12

Most programs can be upgraded in-place. And I've seen a new package 
completely replace an old package in a regular update.

Point taken. I think it's something we've grown accustomed to with 
cutting edge technology.
For me, I consider Fedora users very lucky because we have top notch 
people handling virtually all of the nasties that can destroy a system 
and we have choice, upgrade or not, either way the system keeps on working.

As for kmod-nvidia, I tried a Radeon video card but had no success, gave 
up an went back to nvidia. Things have probably changed since but I'll 
tackle that with F12 on a new computer some time.
