I have to warn others that use OpenSuSE not to try out Tumbleweed unless you are absolutely sure you know what you are doing and you are willing to monitor which software packages are being added from which software repository at all times during a zypper up or dup. I had a lot of problems with OpenSuSE 64 bit Tumbleweed when I mixed software repositories together from third-party software sources. It wound up borking my system.
Stick with the latest version of OpenSuSE 64 bit if you can't handle the constant influx of changes and new stable software packages from Tumbleweed.
Otherwise, I switched back to Ubuntu 12.04.1 64 bit LTS because it's a lot more stable and reliable than OpenSuSE 64 bit Tumbleweed. I can finally relax a little bit and use my System76 PC instead of worrying if my next update will trash my operating system when I used OpenSuSE 64 bit Tumbleweed.
